土壤中总氰化物分析方法的研究

Study of Analysis of Estimating the Total Cyanide in Soil

通过对底泥、土壤中氰化物预处理方法的选择，证明在硫酸介质中蒸馏，用氢氧化钠为吸收液，异烟酸吡唑啉酮光度法测定土壤中总氰化物的分析方法具有准确度高、精密度好等特点。

With the selection of the pretreatments of studge and soil cyanide,we found distillating in sulfuric acid and absorbed by sodium bydroxide solution,the analysis of using iso\|nicotinic acid and 3\|methy\|1\|phenyl\|5\|pyrazolone spectrophotometer to estimate the amount of total cyanide in soil has the high accuracy and good precision.
