摘　　要：综合运用傅里叶变换红外光谱仪、核磁共振波谱仪及X-射线衍射仪等仪器分析法和常规分析法成功剖析了3种国外洗衣粉样品并对每种组分进行了定量分析。分析结果表明,3种洗衣粉样品中的活性物主要为直链烷基苯磺酸钠(LAS)及脂肪醇聚氧乙烯醚(AEO)系列;无机助剂主要为三聚磷酸钠、碳酸钠、硫酸钠。Three foreign powder detergent samples were analyzed by FT IR, NMR, XRD and conventional methods, in which each component was also quantitatively analyzed. The results showed that the major surfactants for the three samples were sodium linear alkylbenzene sulfonate（LAS） and fatty alcohol ethoxylate（AEO） while the major inorganic salts were sodium tripolyphosphate, sodium carbonate and sodium sulfate.
