Development of a Sorption-spectroscopic Method for the Determination of Lead Ions by Immobilized Sulfarsarsen

Abstract

This article defines the optimal conditions for the detection of a heavy metal ion of lead (II) using a newly synthesized PPA 1 sorbent immobilized with a sulfarsazene reagent; PPA 1 and SMA 1 sorbents are selected as sorbents.

The maximum reflectance spectrum of the reagent is 480 nm the maximum light reflectance of the complex is 580 nm (for SMA 1), 570 nm (for PPA 1). The sorption rate of lead exceeds 90% on average.
