n order to investigate the correlation between selenate reduction and nitrate denitrification,a series of related experiments were carried out in different soil-water systems,in which a given amounts of KNO3 and Na2SeO4 solution were added,and the transformation processes of chemical speciation of selenate and nitrate were studied.
为查明土壤中硒酸盐还原作用与硝酸盐脱氮化作用的相关关系,在不同类型土-水系统中,加入一定量的KNO3和Na2SeO4溶液,观察NO和的化学形态转变过程。
