Abstract:

A method for determination of 37 elements in shampoo cosmetics was established by using super microwave digestion-inductively coupled plasma mass spectrometry (ICP-MS). After the samples were digested on a super microwave digester, Re and Rh were applied as internal standard elements, and the concentrations of 37 elements including Pb, As, Hg, Cd, Li, Be, Sc, V, Co, Ni, Cr, Mn, Cu, Rb, Sr, Pr, Nd, Dy, Ag, In, Cs, Ba, Tl, Bi, Th, La, Ce, Er, Eu, Gd, Ho, Lu, Sm, Tb, Tm, Y and Yb were simultaneously determined by ICP-MS. The method has a good linear relationship within a certain concentration range, and the linear correlation coefficients are all≥0.995. The recovery rates of low, medium and high spiked concentrations are 87.1%-113.5%, and the RSD is 0.72%-5.00% (n=6). This method has strong specificity and high sensitivity, which can rapidly and accurately determine 37 metal elements in shampoo products.

Key words: super microwave digestion, ICP-MS, shampoo cosmetics, element
