| Abstract: | 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. |
