【摘要】 本文基于在硫酸介质及100℃水浴加热条件下,痕量钒(V)对过硫酸铵氧化苯羟乙酸生成电活性物质苯甲醛这一慢反应的选择催化作用,建立了一个可测范围为0.04ng/ml-8.0ng/ ml,灵敏快速、选择性较佳的测定水中钒的催化示波极谱法。更多还原

【Abstract】 We find the catalytic oscilloscopic polarography way for determination of Ⅴ in water on the basis of vanadic selective catalytic action in the slow reaction which produces a benzaldehyde compound by ammonium persulfate oxidating benzcnegydro acid.The mcthos has an advantage of high sensitivity,speed and selective action,and can be used to analyse Ⅴ in the concentration scale from 0.04 to 8.00(ng / ml).更多还原
