Effect of Sulfur and Chlorine on the Speciation of Mercury in Coal

Abstract:

Mercury and its compounds which formed in the coalcombustion process have a serious effect on the environment. Four coal samplesin Chongqingwere selected to study on the occurrenceform of mercury, as well as the effect ofsulfur, chlorine on mercury speciation. Results showed that the mercury contentin coal ranged from 257 ng/g to 332.7 ng/g，with sulfur, chlorine content increased，the total mercury content increased，too. The sulfur content in coal ranged from 1.52% to3.54%, the mercury in sulfide and sulfurhave a good correlation, and square of the correlation coefficient (R²)between them is 0.9883. The chlorinecontent in coal ranged from 0.05% to 0.15%，the mercury in organic compound and sulfur have a good correlation，andsquare of the correlation coefficient (R²) between them is 0.9639.
