A Study on H2PO2 - in the Process of Electroless Nickel Plating on Activable Inertia Groups Geng Houan1, Wei Xiwen1*, Li Bing2, Yang Lijun1, Zhang Chaoyang3 (1 Chemistry and Chemical College, Chongqing University, Chongqing 400044 2 Dongbei Institute of Electric Power, Shenyang 110006 3 Institute of Chemical Industry Materials, The Chinese Academy of Eigineering Physics, Mianyang 621900) Abstract In this paper, the structural characteristics and electro-structure of H2PO2- were discussed by means of FTIR and ab initio. The dissociating route of H2PO2-, which is in the process of electroless nickel plating activated by nickel on inertia groups, has been investigated. The average crack and different crack of P-H bond were deliberately analyzed. Moreover, the influence of both solvent and active matter on H2PO2- dissociation was studied.
