摘要
锰是一切生物体内不可缺少的微量元素,与很多生理现象有关。过量的锰却是一种有害物质,某些胆结石患者结石中含有一定量的锰,约占0.72％左右,它与胆结石的形成有着密切关系。目前用于测量胆结石中锰含量的传感器的报道较少。
A manganese(II) selective membrane sensor based on premanganeteceyal trimethylammonium bromide as an electrically active material was investigated. The mangnese(II) sensor showed nernstian response in 10-1~1.08+10-5mol manganesfl(I) solution over pH 5.6-7.3 with a slop of 29.0 mV/decade. The manganese (II) sensor was applied to determine manganese(II) in cholelith gallstone
