摘要
通过N,N-二乙基-1,4-苯二胺分光光度法测定雅安职业技术学院附属医院医疗出水余氯含量,分析不同温度下医疗出水的余氯含量的差异,并对比医疗出水与其他3种不同水样余氯测定结果.确定余氯校准曲线方程为 y=0.209 9x+0.007 9,医疗出水余氯的测定结果依次为 5.336、5.241、5.479 mg·L-1,均值为5.352 mg·L-1,STD为0.120,RSD为0.22,实验结果符合《医疗机构水污染物排放标准》(GB18466-2005)的余氯排放标准.
Abstract
The residual chlorine content of medical effluent from the hospital of Ya'an Vocational and Technical College was determined spectrophotometrically by N,N-diethyl-1,4-phenylenediamine,and the differences in the residual chlorine content of medical effluent at different temperatures were analyzed,and the results of the determination of the residual chlorine of medical effluent and three other different water samples were compared.The calibration curve equation of residual chlorine was determined as y=0.209 9x+0.007 9,and the measured results of residual chlorine in medical effluent were 5.336 mg·L-1,5.241 mg·L-1 and 5.479 mg·L-1 in order,with the mean value of 5.352 mg·L-1,STD of 0.120 and RSD of 0.22.The experimental results were in accordance with the residual chlorine discharge standard in Discharge standard of water pollutants for medical organization(GB18466-2005).
