Особливості використання методів комплексонометричного титрування при вивченні адсорбційних властивостей глинистих сорбентів

We studied the applicability of the complexometric titration to obtain the reliable data on zinc ion absorption on clay minerals. The method can be used for zinc-ion adsorption evaluation but the results of the reference solution titration with acetate buffer (to reproduce acidity of zinc-ion solutions) should be taken into consideration. The absorption capacity of the clay minerals increases after their processing with the hydrochloride acid.
