https://www.selleckchem.com/products/withaferin-a.html The effect of population dominates the changes in water demand in the northern regions, with the exception of the Northwestern Region, where water intensity is the leading factor, possibly because the Balkans' largest nuclear power plant is located in the region. In the southern regions where income is higher, income has been the most important determinant of water demand, particularly in recent years.Lanthanum molybdate/magnetite (M-La2(MoO4)3) with various LaCl3/Fe3O4 mass ratios was synthesized and optimized for selective phosphate removal from wastewater. M-La2(MoO4)3 (21) was selected on the basis of phosphate sorption capacity for further experiments and characterized by a variety of methods. The phosphate sorption kinetics, isotherms, and matrix effect were studied. The maximum sorption capacity at initial pH 7 indicates the possible applicability M-La2(MoO4)3 (21) in removing phosphate from the aquatic environment. Phosphate removal by M-La2(MoO4)3 (21) with high selectivity was achieved in the presence of other co-existing anions, while calcium and magnesium ions were found to inhibit the sorption process. The sorption isotherm study showed that Freundlich and Sips models fit better the Langmuir model, indicating that heterogeneous multilayer sorption was dominant during the phosphate sorption process. Sorption kinetic results showed that the pseudo-first-order kinetic model can describe well the phosphate sorption process by M-La2(MoO4)3 (21). Consecutive sorption-desorption runs showed that M-La2(MoO4)3 (21) could be reused for a few cycles. Simultaneous removal of phosphate and organic matter was achieved in real wastewater by using M-La2(MoO4)3 (21). The sorption mechanism was inner-sphere complexation.A magnetically separable Fe3O4/CuO core-shell heterostructure photocatalyst was synthesized by hydrothermal method. The obtained photocatalyst was characterized by Fourier-transform infrared spectrosc
