METHOD FOR DETERMINING CONTENT OF LEAD

The proposed method for determining content of lead consists in concentrating lead on the surface of the sorbent and comparing the color of the sorbent with the colors of the reference color pattern. As the sorbent, silica gel is used that is modified with the ionic product of the reaction of ammoni...
