Abstract

도금액중 Cl 농도를 분석하기 위한 시료 전처리방법에 있어서, 종래의 AgNO3대신에 NaOH를 첨가하고 또 아르곤 가스를 주입하여 점적용액을 건조시킴으로서 시료처리 과정에서의 Cl 성분의 휘발을 효과적으로 방지할 뿐만 아니라 그로 인하여 도금액 중의 Cl 농도를 보다 정확히 분석할 수 있다.In the sample pretreatment method for analyzing the concentration of Cl in the plating solution, NaOH is added instead of the conventional AgNO 3 and argon gas is injected to dry the dropping solution, thereby effectively preventing the volatilization of the Cl component during the sample processing. Therefore, the Cl concentration in the plating liquid can be analyzed more accurately.
