摘要
污水中酚类化合物的分析一般采用4-氨基安替比林光度法,此法的优点是简便、快速、准确度高。通过计算相对误差和相对标准偏差,查找车间分析过程中的误差来源,进而避免或减少误差。
Phenols content in wastewater is analized by the spectrophotometric method of 4-amino Antipyrine.The advantage of this method are briefness,speediness and high-accuracy.In this paper,we found the soure of error in the procedure of the workshop analysis by calculating the relative crror and relative standard deviation to avoid or reduce the error.
