研究了在柠檬酸存在的硫酸介质中,矿石中的铋与硫脲-碘化钾-马钱子碱络合染色,用三氯甲烷在室温及100r/min条件下震荡4min萃取其络合物.络合物的最大吸收峰位于460nm处,Bi(Ⅲ)含量在0~20μg范围内符合比尔定律,回归方程为Y=0.09967+0.00586X,相关系数r=0.99964.对伊犁尼勒克铜矿矿石溶液进行7次平行测量,结果表明,矿石中原矿、精矿、尾矿铋的含量分别为O.003%、0.00064%、0.0028%,RSD在0.3%~2.O%之间,摩尔吸光系数分别是5.3139×10^4、5.3464×10^4、5.3514×10^4,回收率在96.44%-96.74%之间,该测量方法简便易行.
研究瞭在檸檬痠存在的硫痠介質中,礦石中的鉍與硫脲-碘化鉀-馬錢子堿絡閤染色,用三氯甲烷在室溫及100r/min條件下震盪4min萃取其絡閤物.絡閤物的最大吸收峰位于460nm處,Bi(Ⅲ)含量在0~20μg範圍內符閤比爾定律,迴歸方程為Y=0.09967+0.00586X,相關繫數r=0.99964.對伊犛尼勒剋銅礦礦石溶液進行7次平行測量,結果錶明,礦石中原礦、精礦、尾礦鉍的含量分彆為O.003%、0.00064%、0.0028%,RSD在0.3%~2.O%之間,摩爾吸光繫數分彆是5.3139×10^4、5.3464×10^4、5.3514×10^4,迴收率在96.44%-96.74%之間,該測量方法簡便易行.

Studied the presence of citric acid in the medium, and bismuth ores thiourea - potassium iodide - Brucine complex staining with Chloroform at room temperature and under the conditions of 100r/min concussion concussion 4min extraction instrument its complex. Maximum absorption peak of the complex is located at 462 nm wavelength, Bi (Ⅲ) concentration in the range of 0-20~tg Beer's law is obeyed, the regression equation is Y=0.09967+0.00586X, correlation coefficient r is 0.99964. Nileke solution of copper ore to 7 parallel measurements, the results show that the ore (ore, concentrate, railings) in the bismuth content of 0.003%, 0.00064%, 0.0028%. RSD 0.3%-2.0%, and molar absorptivity is 5.3139 × 10^4, 5.3464 × 10^4, 5.3514 × 10^4, the recovery rate from 96.44% to 96.74%, and the measurement method is very simple.
