摘要
建立了一种快速、简单、准确的试剂盒目视比色法现场快速测定水中氰化物的方法。探讨了温度、共存离子等因素对显色深浅的影响。在最佳实验条件下,氰化物质量浓度在0.005-0.5 mg/L范围内与吸光度呈良好的线性关系,相关系数为0.999 9,与国标法测定结果相近。该方法应用于生活污水和河涌水中氰化物的测定,加标回收率为96.0%-113.0%。
objective A new visual colorimetry of test kit is used for rapid,simple and accurate determination of cyanide in water on site. The effect of temperature and coexistent ions on the chromogenic reaction is studied. Under optimal conditions,the linear concentration for cyanide is from 0. 005- 0. 5 mg / L with a correlation coefficient of 0. 9999,which is close to the results determined by National Standard Method. When this approach is applied to the determination of cyanide in the wastewater and river water,recoveries is in the range from 96. 0- 113. 0.
