Current progress in remediation of chlorinated volatile organic compounds: A review
Chunhao Dai,Yaoyu Zhou,Hui Peng,Shaojian Huang,Pufeng Qin,Jiachao Zhang,Yuan Yang,Lin Luo,Xiaoshan Zhang 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.62 No.-
Chlorinated volatile organic compounds (Cl-VOCs) contamination has been recognized as one of the major problem in worldwide due to natural and anthropogenic activities. Recently, several treatment technologies (e.g., adsorption for broader concentration Cl-VOCs, catalytic combustion for high concentration (>500 ppm), advanced oxidation, electrochemical method, metal method and photocatalytic method for low concentration (<500 ppm)) have been applied for Cl-VOCs elimination. In this review, an extensive list of every method from literatures is compiled, and their capacities under various conditions are presented. However, there is still need to find out the practical technologies on commercial scale, leading to improvement of environmental pollution control.

Persistent organic pollutants (POPs) in soil have caused widespread concern, which is necessary to developefficientand greentechnologies.Electrokinetic (EK)remediationtechnology,theirenhancementtechniquesand composite techniques with other processes have shown broad application prospects in thefield of soilPOPs remediation. In this paper, the progressof EK remediation technology in the remediation of POPs in soilin recent years is reviewed. It can be seen that some technologies need to be further studied and evaluated,and it is inappropriate to simplycompare them.The effectoffield remediation is boundto be affected byfieldconditions,andthefinal datawill be differentfromthelaboratory data. Some emerging technologies,such asadvanced oxidation technology and nanotechnology, demonstrated high POPs removal rates when coupledwith EK remediation technology. This paper provides some insights into the future development of thetechnology and provides reference for the selection of technology in practical application.

<P><B>Abstract</B></P> <P>Elevated level of arsenic (As) in marine sediment via deposition and accumulation presents long-term ecological risks. This study proposed a sustainable stabilization/solidification (S/S) of As-contaminated sediment via novel valorization of red mud waste, blast furnace slag and calcined clay mineral, which were selected to mitigate the increased leaching of As under alkaline environment of S/S treatment. Quantitative X-ray diffraction and thermogravimetric analyses illustrated that stable Ca-As complexes (e.g., Ca<SUB>5</SUB>(AsO<SUB>4</SUB>)<SUB>3</SUB>OH) could be formed at the expense of Ca(OH)<SUB>2</SUB> consumption, which inevitably hindered the hydration process and S/S efficiency. The <SUP>29</SUP>Si nuclear magnetic resonance analysis revealed that incorporation of metakaolin for As immobilization resulted in a low degree of hydration and polymerization, whereas addition of red mud promoted Fe-As complexation and demonstrated excellent compatibility with As. Transmission electron microscopy and elemental mapping further confirmed the precipitation of crystalline Ca-As and amorphous Fe-As compounds. Therefore, red mud-incorporated S/S binder achieved the highest efficiency of As immobilization (99.9%), which proved to be applicable for both <I>in-situ</I> and <I>ex-situ</I> S/S of As-contaminated sediment. These results advance our mechanistic understanding for the design of green and sustainable remediation approach for effective As immobilization.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Stable Ca-As complexes could be formed at the expense of Ca(OH)<SUB>2</SUB> consumption. </LI> <LI> Metakaolin addition for S/S of As resulted in a low degree of hydration and polymerization. </LI> <LI> Incorporation of red mud promoted Fe-As complexation and improved compatibility with As. </LI> <LI> Green binders were applicable for both <I>in-situ</I> and <I>ex-situ</I> S/S of contaminated sediment. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
