以硫脲配位用原子吸收法测定矿石中银

Study of Determination of Micro Amounts of Silver in Ore with Thiourea by Atomic Absorption Spectrometry

本实验是在近中性介质中,以硫脲为配位剂测定岩矿中银的新方法。样品用盐酸、王水、氢氟酸、高氯酸溶解,蒸干后加硫脲配位剂,使用乙炔—空气火焰测定银。

A method for determination of silver in ore by atomic absorption spectrometry was discussed, the precision was tested, and RSD value and the detection limit were obtained.
