New method to determine low content Tin in wastewater was tested. It combined stable temperature platform graphite furnace, undertook correction with vertical Zeeman effect background, took palladium as matrix modifier and peak area integral. 试验了集恒温平台石墨炉(STPF)于一体的纵向塞曼效应背景校正,最大功率升温,钯作为基体改进剂和峰面积积分(A-s)测定废水中低含量锡的新方法。
With addition of modifier, specific surface area increases gradually, of which surface area of the quick lime is relatively large, content reaches 10%, average pore size and total pore volume reach maximum. 随着改性剂的加入,比表面积逐渐增大,其中生石灰的比表面积相对较大,改性污泥内掺量为10%,平均孔径和总孔体积达到最大值。
