摘要
氰化物是一种毒性很强的污染物,因此是安全环保部对油田产能建设工程地下水环境水体监测的一个重要监测项目。常用的检测方法有异烟酸-吡唑啉酮比色法、异烟酸-巴比妥酸比色法,但方法中用来绘制标准曲线的氰化钾是剧毒化学药品。通过实验验证可认为总氰化物溶液标准物质因其稳定、纯度高、便于储存的特点,更适宜替代氰化钾用于绘制总氰化物标准曲线,达到有效控制生产安全事故及环保事故发生的目的。
cyanide is a very toxic pollutant,so it is an important monitoring project of the ministry of safety and environmental protection for groundwater environmental water monitoring of oilfield production capacity construction projects.The commonly used methods are iso-nicotinate-pyrazolone colorimetry and isonicotinic-barbiturate colorimetry,but the potassium cyanide used to draw the standard curve is a highly toxic chemical.It can be concluded that the standard material of total cyanide solution is more suitable to draw the total cyanide standard curve instead of potassium cyanide due to its characteristics of stability,high purity and easy storage,so as to effectively control the occurrence of production safety accidents and environmental accidents.
