摘要：
A chelating sorbent obtained by adsorption of 1-(2-pyridylazo)-2-naphthol (PAN) on Amberlite XAD-2 was used for the preconcentration of Ga and In. The analytical characteristics of the chelating sorbent were investigated and optimun sorption conditions for these metals under dynamic conditions were established. A peristaltic pump is used to adjust the flow rate of the solution. Elements are collected from the column by using a mixture adjusted to a pH range of 4-7 and 6-12 by ammonia or ammonium chloride for Ga and In, respectively. The procedure developed was applied to the analysis of different ores.
