利用30mW氦-氖激光器,用苯萃取汞-孔雀石绿溶液于二氯甲烷中,在2cm液槽中对汞作了测定,最低检测浓度0.05ppb,并初步用于尿中汞的测定.
Mercury was measured in a 2 cm cell using a 30 mW He-Ne laser with benzene-extracted mercury-malachite green solution, with a minimum detectable concentration of 0.05 ppb, and was initially used for the determination of mercury in urine.
