高钠煤中钠的赋存形态研究
Occurrence modes of sodium species in sodium-rich coals
摘要
Abstract
The occurrence modes of sodium species and corresponding content distributions in sodium-rich coals were investigated through a series of analytical methods.The results indicate that for the vast majority of coals sodium are mainly in the form of water-soluble form,then organic form,and the content of insoluble form is negligible.Among them,the water-soluble sodium is mainly presented as nitratine (NaNO3),halite (NaCl)and hydrated ion (Na·xH2O).The organic sodium is mainly presented as carboxyl sodium (-COONa),while the insoluble sodium mainly occurs as albite (NaAlSi3O8).关键词
