摘要
研究了分光光度法测负载型钼催化剂中钼含量的分析方法.找到了测定范围内的最佳吸收波长、pH值、试剂用量和测定时间,作出了工作曲线.确定了符合比尔定律的线性范围和测试液浓度下限(10^(-5)～10^(-6)mol/L).其测定的相对误差为2%～5%.
The method of meassuring molybdenum loading of supported catalyst has been studied with spectropho-tometry. The optimum absorbed wavelength, pH value, usage of reagents and time of meassuring have been giv-en. Working curve has been worked out. The linear rang of Bille law and the lowest concentration of samples (10^(-5)-10^(-6)mol/L) were obtained. The relative error of determination is 2%-5%.
