A polyaniline / polyisoprene composite film with permselectivity was synthesized by electrochemical method for the first time , which can determine selectively h2o2 in the presence of electroactive interferent ascorbic acid 采用電化學(xué)方法首次制備了具有特殊滲透選擇性的聚苯胺/聚異戊二烯復(fù)合膜,它能在抗壞血酸存在下讓過氧化氫選擇透過。
The zircondri filin wtut rirconia wa prepared and the removing technology of the zirconia on the zirconium sdrices was obtalned . the methods of chemistry and magnetron sputtring plating were used in order to platc a palladium film , which is characteristic of self catalysis for hydrogen and the sole h - permselectivity on the clean rirconium sdrices prepared by the methods of electrochemitw and ( or ) high temperatur vacuum hydrgenization , which was firstly studied . the plating tedrilogy was obained and the surface modified zirconium membran was prepared 在利用電化學(xué)法和真空高溫除氧加氫法去除了鋯表面氧化膜的基礎(chǔ)上,分別采用化學(xué)法、磁控濺射法兩種鍍膜技術(shù)在其表面上鍍上了一層對(duì)氫具有自催化分解、唯一選擇滲透性的金屬鈀膜,首次獲得了鋯基材膜表面上鍍鈀的制備工藝,成功制備了鋯表面改性選擇滲氫膜。
