| Abstract: | A method for the determination of the contents of Fe,Cu and Pb in the wet digestion solution and supersonic solution of honeysuckle was established by FAAS.The contents of three elements in honeysuckle were FeCuPb.Dissolution rates of the elements were CuPbFe with hydrogen nitrate as extractant.The recoveries of these trace elements were in the range of 85%—107% and the relative standard deviation was between 0.6% and 1.0%.The elements can be better extracted by supersonic wave,and the dissolution rates does not depend on the size of the total elements in Chinese herbs.FAAS is rapid,simple,high precision,good accuracy and sensitivity to determine the elements in the honeysuckle. |
