锰在生物化学方面是一个重要的元素,也是在人体中一种必需的痕量元素,但超过正常量时又是典型的有毒元素.缺锰及锰中毒在临床上可引起一系列疾病.目前国内外有关人发中痕量锰的分析方法有中子活化法,原子吸收光谱法,X 光荧光光谱法及电感耦合等离子发射光谱分析法等.未见到用脉冲极谱结合溶出伏安法测定发锰的文献报导.本文采用国产的 F-78型脉冲极谱仪,旋转玻碳汞膜电极为工作电极,用差分脉冲阳极溶出伏安法,以0.01mol/L NaNO_3为支持电解质,测定了人发中痕量锰,并对
Manganese is an important element in biochemistry and an essential trace element in the human body, but it is also a typical toxic element when it exceeds the normal level. Manganese deficiency and manganese poisoning can cause a series of clinical problems. At home and abroad on human hair trace manganese analysis methods include neutron activation method, atomic absorption spectrometry, X-ray fluorescence spectrometry and inductively coupled plasma emission spectrometry, etc. There is no pulse Polarography combined with stripping voltammetry Determination of manganese in the literature reported.In this paper, the domestic F-78 pulse polarography, rotating glassy carbon mercury electrode as the working electrode, with differential pulse anodic stripping voltammetry to 0.01mol / L NaNO_3 as supporting electrolyte measured Human hair traces of manganese, and right
