Recent Status on Methods of Determination of Arsenic in Coal and Researches of Endowed Species of Arsenic in Coal

A review of the recent status of methods of determination of total arsenic in coal and researches on endowed species of arsenic in coal, covering mainly the years of last decade was presented, relating especially the topics on the pretreatment of coal samples in the determination of total arsenic, various methods used in the determination of arsenic in coal and researches on the endowed species of arsenic in coal, as well as the extraction of various species of arsenic individually from the coal sample. A forecast on the future progress of the related problems mentioned above, especially on the speciation analysis for arsenic in coal was also given (35 ref. cited).
