【摘要】 采用HCS - 1 40型红外吸收碳硫分析仪同时测定贵金属催化剂中的碳、硫含量。试验了助熔剂种类、用量、样品量对测定的影响 ,用异标校正测定了多种类型贵金属催化剂中的碳、硫。取得了满意结果 ,方法的相对标准偏差为 0 2 %～ 7 7%更多还原

【Abstract】 A method has been established for determination of carbon and sulfur in catalysts of precious metals with HCS-140 type infrared spectrometry.The influence of different assistant fluxes and their used quantity as well as the quantity of sample on the determined results has been investigated.The determination results of carbon and sulfur in various kinds of precious metal catalysts were corrected by the different standard with satisfactory results.The relative standard deviation was 0 2%～7 7%.更多还原
