| Abstract |
Description of a method of determination particularly well suited for early screening for arsenic poisoning. The method is based on the conversion of arsenic in urine into arsine by reduction, using sodium borohydride, and on the thermal decomposition of arsine into elemental arsenic, which appears in the atomic absorption spectrometer. Description of preparation of the sample, method of determination, set-up required, reagents and results of recovery tests. Reliability criteria of the method are shown in a table. The limit of detection is 14µgAs/l urine; the recovery percentage is 90-100%. |
