本文研究了Hg~(2+)-Ⅰ~-络离子在SnCl_2存在下与结晶紫-PVA形成离子缔合物的浮选分离分光光度法,其摩尔吸光系数ε为3.26×10~6L/mol·cm,用本法测定了香烟和自来水中的微量汞。
In this paper, the flotation separation spectrophotometry of Hg 2+ ion complexed with crystal violet-PVA in the presence of SnCl 2 was studied. The molar absorptivity ε was 3.26 × 10 -6 L / mol · Cm, using this method of determination of trace amounts of mercury in cigarettes and tap water.
