| 摘 要： | 研究了铋、氧化铋、硫化铋在硝酸-硫脲中的溶解性。三价铋离子与硫脲溶液可形成黄色络合物,在波长为460nm处,反应温度为25℃,反应时间为6min,硝酸浓度为1.0mol/L,硫脲浓度为0.5mol/L,振荡速率为160r/min条件下铋含量在0.059—4.57μg/mL范围内服从郎伯-比尔定律,检出限为m=0.04μg。铋矿物的溶解性顺序大小为Bi2O3>Bi>Bi2S3。本方法操作简便,可靠,实验结果满意,具有广泛的实用意义。

| Abstract: | Solubility of bismuth,bismuth oxide and bismuth sulfide in nitric acid-thiourea was studied.The yellow complex was formed by trivalent bismuth ion with thiourea solution.The concentration of bismuth obeyed Lambert-Beer law in the range of 0.059-4.57μg/mL under the conditions as follows:the wavelength of 460nm,the reaction temperature of 25℃>the reaction time of 6min,the nitric acid content of 1.0mol/L,the thiourea concentration of 0.5mol/L and speed of 160r/min,and the detection limit of 0.04μg.The solubility of bismuth minerals was in order of size bismuth oxide > bismuth > bismuth sulfide.The method is simple and reliable with satisfactory results,and has the wide use of significance. |
