摘要
介绍了４种对钯有高灵敏和选择性的安替比林偶氮胂酸类试剂。试剂在较高酸度介质中能与钯形成稳定的２：１红色络合物。表观摩尔吸光系数为３．５～５．１×１０４。用ＡＡＡＴＡＲ测定镍铜合金中的钯，结果满意。
Four new antipyrinylazo arsonic acid reagentshave been reported as highly sensitive and selectivechromogenic reagents for palladium in this paper.Allfour reagents can form stable 2: 1 red chelates withPd(Ⅱ) in strong acid media, their apparent molarabsorptivities are 3. 5～5. 1 × 104 L· mol-1· cm-1 .The reagent AAATAR has been applied to the determinationof palladium in Ni-Cu alloy with satisfactory results.
