To provide a method for subjecting the surface of an ABS based resin free from chromium and manganese to plating pretreatment, capable of forming plating sufficiently stuck to the surface of the ABS based resin.SOLUTION: An apparatus 1 for subjecting an ABS based resin to hydrophilic treatment includes a treatment tank 2 having a thermostatic heater 3 provided in the outer periphery and a supply tank 6 connected through a pipe line 4 and a pump 5. Persulfate solutions S and S1 having a predetermined sulfuric acid concentration and persulfuric acid concentration are charged into the treatment tank 2 and the supply tank 6, respectively; an ABS resin plate 7 as an ABS resin to be treated is suspended and treated in the vertical direction in the treatment tank 2; and the persulfate solutions S and S1 have a sulfuric acid concentration of 60-87wt%, a persulfate acid concentration of 2 g/L or more and a temperature of 50-85°C.SELECTED DRAWING: Figure 1 【課題】クロム及びマンガンフリーのＡＢＳ系樹脂表面のめっき前処理方法であって、ＡＢＳ系樹脂表面に十分に密着しためっきを形成することができるＡＢＳ系樹脂表面のめっき前処理方法を提供する。【解決手段】ＡＢＳ系樹脂の親水化処理装置１は、外周に恒温ヒータ３が設けられた処理槽２と、配管４及びポンプ５を介して接続された供給槽６とを有する。処理槽２及び供給槽６には、所定の硫酸濃度及び過硫酸濃度の過硫酸塩の溶液Ｓ，Ｓ１がそれぞれ充填されている。そして、処理槽２内には、被処理ＡＢＳ系樹脂としてＡＢＳ樹脂板７が上下方向に吊設されている。この過硫酸塩の溶液Ｓ，Ｓ１の硫酸濃度は６０〜８７ｗｔ％であり、溶液Ｓ，Ｓ１の過硫酸濃度は２ｇ／Ｌ以上である。また、溶液Ｓ，Ｓ１の温度は５０〜８５℃である。【選択図】図１
