本文用电解氢化物发生-原子吸收法测定人尿中的砷,结果与硼氢化钾法十分吻合。方法基于在电解池中阴极池和阳极池由导电不透气膜隔开,电极均为铂片(0.4×0.5cm)制成。电解时,在阴极上生成的氢基(H~*),可使能被氢化的离子还
In this paper, electrolytic hydride generation - atomic absorption spectrometry for determination of arsenic in human urine, the results with the potassium borohydride method is very consistent. The method is based on that in the electrolytic cell the cathode and anode cells are separated by a conductive gas-impermeable membrane, the electrodes being made of platinum sheets (0.4 x 0.5 cm). During electrolysis, the hydrogen radicals (H ~ *) generated on the cathode enable the hydrogenated ions to be repressed
