摘要
利用30mW氦-氖激光器,苯萃取铊-孔雀石绿溶液,于氯仿中,2cm液糟中,对铊作了测定,最低检测浓度0.05ng/ml,并用于自来水回收实验。
The thallium-malachite green complex can be extracted by benzene from water solution and is applied to the measurement of its lases thermal lens effect for determining trace level Tl (Ⅰ).Using a 30 mW He-Ne Laser (wavelength 632. 8μm), 2cm sample cell and CHCl_3 solvent, a minimum detectable concentration and linear range of thallium are 0.2ppb and 0.2—4.0ppb respectively.
