The adsorptive potential of De-Acidite FF-IP resin for the removal of nitrate (NO3) from synthetic as well as commercially available bottled water samples was testified. Ultra-performance liquid chromatogra-phy–mass spectrometry (UPLC–MS) was utilized for detection and determination of NO3 . Optimum NO3 adsorption was observed at pH range 2 to 6. Kinetic studies revealed the applicability of pseudofirst-order kinetic model for analyzed concentration range (100–300 mg/L) while, the equilibration time (25 min) was independent of initial NO3- concentration. The breakthrough capacities in Milli-Q and tap water were 35 and 30 mg/g, respectively.

The present work deals with the removal of highly toxic Cd2+from wastewater using ecofriendlycurcumin (7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione) formaldehyde resin (CFR). The CFR resin was characterized using several analytical techniques. The adsorption kinetics andisotherms were well fitted by pseudo-second-order and Freundlich models, respectively. The adsorptionof Cd2+ onto CFR was increased with the ionic strength (NaCl). The regeneration studies demonstrated adecrease in the adsorption of Cd2+ from 94% to 80% after five consecutive cycles. All results illustratedthat CFR was a promising adsorbent for the environmental pollution cleanup.

In the present paper, Amberlyst-15 resin was used for the removal of malathion. Various experimentalparameters such as effect of pH, contact time, resin dose, initial malathion concentration andtemperature were studied to find the optimum conditions for malathion removal. The removal rate ofmalathion by Amberlyst-15 was rapid and equilibrium was established within 30 min. Kinetic studiesshowed better applicability for pseudo-second-order model and equilibrium data was best fitted toFreundlich isotherm model. The thermodynamic parameters showed that the adsorption of malathionwas feasible, endothermic and spontaneous. The concentration of malathion was determined usingultra-performance liquid chromatography–tandem mass spectrometry.

Polyaniline Sn(IV) tungstomolybdate nanocomposite (PSTM) was synthesized by sol–gel method. Thephysico-chemical properties of PSTM were studied using FTIR, TGA, XRD, SEM, and TEM. The materialwas successfully used for the removal of Pb2+. Batch experiments were performed as a function of variousexperimental parameters such as effect of pH (2–8), contact time (5–60 min), initial Pb2+ concentration(10–30 mg L 1) and temperature (20–50 8C). The removal rate of Pb2+ using PSTM was fast andequilibrium established within 50 min. Kinetic studies showed better applicability for pseudo-firstordermodel. The values of thermodynamic parameters (DG8, DH8 and DS8) were also computed.

A mesoporous magnetic zirconium phosphate was prepared for the removal of Hg2+ from aqueous medium. The saturation magnetization of pure Fe3O4 and Fe3O4@ZrP was observed 82.9 and 62.4 emu/g, respectively. The effect of different adsorption parameters was studied. The kinetic data were fitted to the pseudo 1st and pseudo 2nd order models whereas the adsorption process was best fitted into the pseudo 2nd order model. The adsorption isotherm could be well described with Langmuir model, with the maximum adsorption capacity of 181.8 mg g1 at 25 C. Thus, the present studies suggested that Fe3O4@ZrP have remarkable potential for Hg2+ removal from contaminated water.

A composite material polyaniline-Zr(IV) phosphoborate (PZPB) was synthesized via sol-gel method by the combination of Zr(IV) phosphoborate and polyaniline. The PZPB composite material was characterized by various analytical techniques. The PZPB composite material was found to be selective for Hg2+ metal ion due to the high distribution coefficient values for Hg2+ metal ion in all mediums. The PZPB composite material was used for Hg2+ removal under different experimental conditions. The antibacterial activity of PZPB composite material was also studied against E. coli.

Fig sawdust was used as a precursor for the production of activated carbon by chemical activation withH3PO4. The developed Fig sawdust activated carbon (FSAC) was used as a biosorbent for the removal ofPb(II) from aqueous solution. Highest adsorption of Pb(II) (95.8%) was found at pH 4. Equilibrium datafitted very well with the Langmuir isotherm model. Maximum adsorption capacity was determined80.645 mg g1 at pH 4. Kinetic studies demonstrated that the adsorption followed a pseudo second orderkinetics model. The negative value of DG8 confirmed the feasibility and spontaneity of FSAC for Pb(II)adsorption.

A glassy carbon electrode (GCE) was tailored with conducting polymer polythiophene and further immobilized by an enzyme glucose oxidase (GOx). A thin film of polymer was developed by electrochemical polymerization of thiophene monomer. During electrochemical polymerization of the monomer the enzyme GOx and the redox active mediator ferritin (Frt) were entrapped within this polymer matrix. In this novel approach, the entrapment of enzyme and mediators within a polymer matrix occurs without chemical reaction that could affect their activity. The entrapment of enzyme and mediator within the conducting polymer matrices increases the surface area of the electrode. The tailored GCE/Ptp/Frt/GOx electrode showed a high catalytic activity. The increased surface area causes a high rate of electron transfer between the electrode and Frt engaged as an electron transfer mediator. The electrochemical properties of the electrode were determined by cyclic voltammetry (CV) and linear sweep voltammetry (LSV). The fabricated bioanode showed a current density of 3.9mA cm−2 at 1.0 V vs. Ag/AgCl in a 45 mM glucose solution and suggests proficient chances in biofuel cells (BFCs) applications.

The electrochemical method has been investigated for the synthesis of copper oxide nanoparticles (CuONPs) under different reaction conditions. The CuO NPs were used as excellent photocatalyst for thedegradation of different organic dyes under the illumination of sunlight irradiation. The highestdegradation was 93% for methylene blue.

A new bio-polymer based nanocomposite, pectin zirconium(IV) selenotungstophosphate (Pc/ZSWP) wasprepared via sol–gel method. The material was characterized using scanning electron microscopy, X-raydiffraction, transmission electron microscopy and Fourier transform infrared spectroscopy. Distributioncoefficient, thermal stability, elution behavior and pH titrations were investigated to explore the ionexchange behavior of nanocomposite. Pc/ZSWP exhibited higher ion exchange capacity (1.27 meq g-1)than its inorganic counterpart (0.67 meq g-1). To explore environmental applicability of the Pc/ZSWP,binary separation and selective separation of Cu2+ and Th4+ from synthetic mixtures of metal ions wereachieved. Antimicrobial activity of the Pc/ZSWP was also investigated.
