| 中文摘要: |
| 利用CN-在苯偶姻缩合反应中的催化作用建立催化快速法，结合测试管法与便携式分光光度法的优势，提出新型氰化物快速定量测定法，并优化该方法的试验条件，使方法在0 mg/L~0.200 mg/L范围内线性良好，检出限为0.005 mg/L。将该方法用于测定氰化物有证标准物质，6次测定结果的RSD为0.5%～2.6%，实际水样的加标回收率为85.0%～110%。该方法与国标法的比对试验表明，2种方法测定结果无显著性差异。 |

| Using catalysis of CN- in benzoin condensation combined with portable spectrophotometry and testing tube method, a new catalytic rapid method was established and was optimized. The method showed good linearity in concentration ranged from 0 mg/L to 0.200 mg/L with the detection limit 0.005 mg/L.The application of this method for a certified standard material determination showed that the RSDs of six measures ranged from 0.5% to 2.6%, and the recoveries of practical water samples were 85.0%〖KG-*4〗~110%. This method had no significant differences with national standard method. |
