【摘要】 采用离子交换分离法,去除铁、铬等离子的干扰,使沉积物中痕量硒的荧光测定法可应用于成分较复杂的沉积物中硒的测定。通过对我国部分海区样品的测定,得出了沉积物中硒的含量,以及晒在沉积物中的富集速率。更多还原

【Abstract】 The fluorescent determination of trace selenium in the sediments may be applied to the detection of selenium in the sediment with complex components by using the ion-exchange separation method and eliminating the interference by such ions as iron and chromiums. The content of selenium and its enriching rate in the sediment have been obtained by measuring the samples in part of China’s sea area.更多还原
