英文摘要	钴(Ⅱ)离子与半胱氨酸的极谱催化波已研究得很多。本文对钴(Ⅱ)离子与色氨酸在H_3BO_2-NaOH(pH=9)缓冲底液中的极谱催化前波进行了形成条件、吸附性能和电极还原过程的研究。; A new polarographic prewave of Co(II) with tryptophan (Trp) in borate buffer (pH = 9) is reported. The adsorption characteristics of tryptophan and its complex Co(II)-Trp, which was formed at the surface of static mercury drop electrode were investigated. The complex has a composition of 1:1 and corresponds to a prewave, while another complex of composition 1:2 may be formed at a more negative potential than the reduction potential of the hydrated Co(II) ion. By the method of double-step chronocoulometry, the area of the adsorbed 1:1 complex was found to be 0.97 nm2.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1992HJ43800008&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 1; 01; 39-43; 50
