ことを特徴とするパラジウムの回収方法。(Means for Solving the Problems) The present invention provides a method for recovering palladium from an acidic solution containing palladium and also containing base metals, ammonium salts, etc. A method for recovering palladium, which comprises preparing the palladium to a pH 3.0 and adsorbing palladium by contacting it with a chelate resin.
前記パラジウムを含む酸性溶液のＰＨを０．１〜３．０
にするには、水酸化ナトリウム等のアルカリを加えて調
製する。The pH of the acidic solution containing palladium is 0.1 to 3.0.
To prepare it, add an alkali such as sodium hydroxide.

との接触の妨害となる等の原因を生ずるからである。PH 0. The reason why the value is 1 to 3.0 is because if it is less than 0.1, the chelate resin will deteriorate in strong acidity, and if it is more than 3.0, the base metals contained in the acidic solution will be hydrolyzed and hydroxide will be produced. This is because they may form and float, interfering with the contact between the chelate resin and the acidic solution.
好ましくはＰＨ＝０．５〜１．５である。Preferably the pH is 0.5 to 1.5.
また、酸性溶液とキレート樹脂との接触方法としてはと
