摘要
研究了用带电导检测器的离子色谱对配煤、焦炭和焦油中的Cl- 进行测定的方法。在YSA型8126A-4# 阴离子分离柱上用3.5mmol/LNa2CO3、5.3mmol/LNaHCO3做淋洗液对Cl-进行测定,方法简便快速。Cl-的检出限为2×10-6。该法也适用于F-、NO2-、NO3-、SO42-等的测定。
A rapid and simple method for the chloride quantity determination in coal, coke and tar from co-carbonization of coal with and without plastics by IC with conductivity detectors is studied. A solution containing 3.5mmol/L Na2CO3 and 5.3mmol/ L NaHCO3 is used as a drip washing liquid on YSA 8126A-4# negative ion column. The detection limits of Clˉ is 2×10-6. This method can also be used for the determination of nitrate, nitrite, fluoride, sulfate ions, etc. in coal, coke and tar. By contrast with other ways, IC is not only simple and convenient, but also accurate.
