Herein, novel silica particles modified with a new bispyrazolylpropane Schiff base were synthesized and characterized using relevant physical techniques. The resulting hybrid material (SiNAL3) was studied for its ability to uptake ZnII, CuII, PbII and CdII ions in aqueous solution via kinetics studies. The maximum adsorption capacities of SiNAL3 for ZnII, CuII, PbII and CdII were approximately 1.23, 0.32, 0.29 and 0.23 mmol g−1, respectively, with an equilibrium reached after only 25 min for all metals. The adsorption process was found spontaneous and endothermic. Interestingly, our hybrid material could selectively adsorb ZnII in the presence of other metal ions from an aqueous solution, a useful property which was applied to real water samples. The adsorbent can be easily reused with no significant decrease in adsorption capacity after not less than five adsorption-desorption cycles, demonstrating its high stability.Lire moins >
