摘要
本文在现用方法的基础上,通过实验进一步优化和改进分析条件,从实验结果可以看出,改进后的分析方法提高了废水中氰化物含量测定结果的准确度和精密度。
On the basis of the present method, the analytical conditions are further optimized and improved through experiments. It can be seen from the experimental results that the accuracy and precision of the determination results of cyanide content in waste water can be improved by the improved analytical method.
