The release of chlorine in the electrodeionization (EDI) unit causes corrosion in the EDI unit, damaging ion exchange membranes and creating a safety risk for the workers. In this work, adsorption desalination of Cl ions on low-cost composite synthetic–natural Jordanian materials were investigated as an approach to prevent the release of corrosive chlorine gas at the positive electrode. The percentage removal reaches 25% at 25 min shaking time to 55% at 120 min, in a single batch experiment. The values of DH0, DS0, and DG0 indicate the favorability of physisorption. Zeolite and Pozzolana represent potential adsorbents of chloride.

This study investigated a mechanochemical process for synthesizing slow-release fertilizers of kaoliniteand KH2PO4/(NH4)2HPO4 in separate systems by milling in a planetary ball mill. Tests with kaolinitecontents ranging from 25 to 75 wt % and mill rotational speeds at 600 rpm for 2 h were performed toevaluate incorporation of KH2PO4 and (NH4)2HPO4 and release of K+, NH4+ and PO43 ions into solution. X-ray diffraction (XRD), Thermal gravimetric analysis (TGA), Fourier transformation infraredspectrometry (FTIR) and ion chromatography (IC) were used to analyze the synthesized samples andindicated that the mechanochemistry (MC) process was successfully applied to incorporate both KH2PO4and (NH4)2HPO4 into the amorphous kaolinite structure. Release of K+ and PO43 ions from the system(kaolinite–KH2PO4) when dispersed in water for 24 h reached up to 15 to 40 ppm respectively. Undersimilar conditions for the system (kaolinite–(NH4)2HPO4), release of NH4+ and PO43 ions reachedbetween 303.2 and 415.1 (ppm) respectively. These results indicated that the MC process could developedto allow amorphous kaolinite to act as a carrier of K+, NH4+ and PO43 nutrients to be released slowly foruse as fertilizer.
