The Determination Research Progress of the Metal Trace Element Iron Copper Zinc Magnesium Calcium by Spectrophotometry

Currently,the determinational methods of five trace elements that are iron,copper,zinc,magnesium,calcium in traditional Chinese medicines,vegetables and food etc.,contain atomic absorption spetrophometry,inductively coupled atomic emission spectrometry,capacity method,spectrophotometry etc.Among them,spectrophotometry has the value to be expanded and universally used because it is simple,rapid,accurate and dosen't need expensive instrument.According to the relative reports both in the domestic and abroad,this article is an overview of determinatiion of this five trace elements by spectrophotometry.
