摘　　要：针对《固体废物有机质的测定灼烧减量法》(HJ 761-2015)存在适用范围有限、干扰因素较多等问题,提出采用红外碳硫仪测定固体废物中有机质的方法,试样经盐酸预处理,低温烘干后,通过红外碳硫仪测定试样中的有机碳,从而计算出有机质的含量。本法适用于不含单质碳的固体废物样品,测量范围:0.0024%~60%,检出限为0.0006%,测定下限为0.0024%,样品测定相对标准偏差1.1%~3.3%。The application scope is limited,there are many interference factors of Solid waste-Determination of organic matter-Ignition loss method(HJ 761-2015),it proposed the determination method for solid wastes by infrared carbon sulfur meter,samples were treated by hydrochloric acid pretreatment,low-temperature drying treatment,measuring of organic carbon was carried out by infrared carbon sulfur meter,accordingly,the content of organic matters can be calculated.The method is proper for solid waste samples without carbon,the measurement range is:0.0024%~60%,the detection limit is 0.0006%,the determination lower limit is 0.0024%,the measuring relative standard deviation of the sample is 1.1%~3.3%.
