title: [Comparative study on trace elements in natural colored cotton and white cotton].
abstract: A method was studied for simultaneous determination of multi-elements in natural colored cotton by microwave digestion and ICP-AES. The contents of Ca, Mg, Fe, Cu, Ba, Zn, Al, Sr, Mn and Si in colored and white cotton were determined by this method. The recovery ratio obtained by standard addition method ranged between 93% and 111%, and the relative standard deviation was below 4% (n = 5). The results showed that the contents of Ca, Cu, Zn, Al, Fe, Sr and Si in green and brown cotton are higher than those in white cotton. The data from the study gives some references for further researches on the colored cotton.
