摘要
在氢氧化钠-硼砂的底液体系中对金矿石进行极谱测定,在峰电位-0.35 V,砷的质量浓度在2～400μg/mL之间时砷的浓度与峰电流成线性关系。选用含有甘露醇的氢氧化钠硼砂的底液测定砷,精度好,准确度高,检出限为0.002μg/mL。
Arsenic in gold ore was determined by polarography in mannitol-sodium hydroxide-borax system.Its peak voltage was-0.35 V,arsenic content had a linear relationship with the peak current when arsenic content was in the range of 2～400 μg/mL.The results show that the method is accurate and reliable,detection limit is 0.002 μg/mL.
