《GB/T 9735-2008化学试剂 重金属测定通用方法》由TC63(全国化学标准化技术委员会)归口,TC63SC3(全国化学标准化技术委员会化学试剂分会)执行,主管部门为中国石油和化学工业联合会。
This national standard specifies the general method "converting the heavy metal in acetic acid medium (PH 3 ~ 4) to sulphuret and determinating with visual colorimetry".
This standard is applicable to the determination of heavy metal (Pb) in chemical reagent. The determination range of Saturated hydrogen sulfide solution colorimetry is 0.3 ~ 2μg/mL (Pb). The determination range of sodium sulfide - glycerin colorimetry is 0.4 ~ 3μg/mL (Pb)
