摘　　要：碘吸附值是衡量活性炭质量优劣的重要指标,该实验以GB/T 12496.8—2015中(150±5)℃烘箱法为参考,用卤素水分测定仪HX204确定木质活性炭快速检测方法主参数为温度130℃,加热模式标准,关机模式1 mg/32 s。用卤素水分测定仪测定的水分计算干基碘吸附值,与烘箱法测定的碘吸附值相对标准偏差为1.36%,在误差允许范围,两种方法碘吸附值无显著差异。The iodine adsorption value is an important index to measure the quality of active carbon.Using the(150±5)℃oven method in GB/T 12496.8—2015 as a reference,the main parameters for rapid determination method of wooden activated carbon were determined by the halogen moisture analyzer HX204,which was temperature 130℃,standard heating mode,and shutdown mode 1 mg/32 s.The dry iodine adsorption value was calculated with moisture determined by the halogen moisture analyzer,and the relative standard deviation was 1.36%compared with the iodine adsorption value determined by the oven method.There were no significant differences between the two methods in the allowable range of error.
