摘要
基于在硫酸介质中,微量Cr(VI)能显著催化KBrO4氧化罗丹明B褪色。建立了测定痕量Cr(VI)新的分析方法,线性范围是0.02～2.0μg/ml,具有高选择性,高灵敏度,摩尔吸光系数为1.3×105L.mol-1.cm-1,应用于废水及环境水中的Cr(VI)的测定,结果令人满意。
Based on the catalytic effrace of tract chromium (VI) on the oxidation of Rhodami with potassium baomate in the medium of H2SO4 a determination methed of chromium(VI) was established by catalytic spectrophotometry. The linear range of the determinaition is 0.02-2.0 g/ml and the molarabsorptivity of reaction is 1.3×105L.mol-1.cm-1. the method is used for the determination of chromium(VI) in water with satisfactory aesults.
