FIELD: analytical methods. SUBSTANCE: method of analyzing solutions containing palladium chloride complexes is based on sorption of these complexes from solution with HCl acidity at least 4 M and pH 4 in dynamic mode (solution passage rate 1-5 ml/min) or static mode (contact time 5-10 min). As sorbent, silica gel modified by thiourea derivatives is used. Method enables efficiently recovering palladium from dilute solutions in content range from 1 to 1000 mcg per 0.1 g of sorbent. Analytical signal utilized is reflection of colored sorbents. EFFECT: increased accuracy. 2 tbl
