METHOD FOR DETERMINING CONTENT OF LEAD BY SORPTION-SPECTROSCOPIC ANALYSIS

摘要

The proposed method for determining content of lead by sorption-spectroscopic analysis consists in concentrating lead on the surface of the sorbent, with pH = 4.8 à 5.3, and determining the coefficient of diffusion light reflection for the painted sorbent. As the sorbent, silica gel is used that is modified with the ionic product of the reaction of ammonium quaternary salt with orange xylenol dye.
