Abstract

PURPOSE:To easily and efficiently separate a platinum group element by treating a platinum group metal, while heating the same, in a gaseous mixture atmosphere containing gaseous chlorine, inert gas and reducing gas. CONSTITUTION:A boat 2 contg. a sheet 1 of Pt-33%Ir is housed in a chloridizing vessel 3 and the vessel 3 is heated to about 700 deg.C in an electric furnace 4. Gaseous Cl2 is then admitted through an introducing pipe 5, gaseous Ar through an introducing pipe 6 and gaseous Co through an introducing pipe 7, respectively into the vessel 3. The total flow rate of the gases is set at 1l/min and the ratios are set at about 45% Cl2, about 50% Ar, and about 5% Co. After the volatile matter generated in such a manner is condensed in a cooling trap 8, the inside of the vessel is purged by the gaseous Ar. About 98% Pt is thus obtd. in the boat 2.

ものである。Detailed Description of the Invention (Industrial Field of Application) The method of the present invention comprises treating a platinum group alloy in a gas atmosphere containing chlorine gas or an inert or/and reducing gas in chlorine gas. This relates to a method for separating group elements.

白金族元素を分離、回収することは工業上重要である。(Conventional technology and its problems) Platinum group alloys have been widely used in heat-resistant materials and scientific instruments, but all of these platinum group elements are expensive and have limited resources. Therefore, it is industrially important to separate and recover these platinum group elements.

従来の方法としては、塩酸溶解法、王水溶解法等がある

能となる。(Structure of the Invention) The present invention provides a method for separating platinum group elements, in which a platinum group alloy is heated and treated in a chlorine gas or a mixed gas atmosphere in which an inert gas and/or a reducing gas is added to chlorine gas. This makes it possible to separate the specific platinum group element by dissociating it due to temperature and/or chlorine partial pressure and moving the undissociated platinum group element from the reaction part as a gas phase.

反応部分の温度は１５０℃以上で行うのが好ましい。The temperature of the reaction part is preferably 150°C or higher.
