摘要：

We have developed the technique of the atomic-absorption determination of barium in drinking and natural waters including its concentration by coprecipitation with lead chromate, dissolution of deposits and measuring atomic adsorption in the acetylene-dinitroxide flame. The concentration coefficient is equal to 1 × 102 at the sample volume of 1 dm3, the degree of barium extraction at the concentration 0.05–0.2 mg/dm2 constitutes from 90 to 100%.
