      heavy metal ions to analysis of skin whitening cosmetics using ICP-AES.

AB  - A novel and highly sensitive method for the determination of some heavy metals in 
      skin whitening cosmetics creams using multiwalled carbon nanotubes MWCNTs as 
      solid phase extraction sorbent for the preconcentration of these heavy metals 
      prior to their determination by inductively coupled plasma atomic emission 
      spectrometry is described. Different practical parameters have been thoroughly 
      investigated and the optimum experimental conditions were employed. The developed 
      method was then applied for the determination of arsenic, bismuth, cadmium, 
      mercury, lead and titanium in samples of skin whitening cosmetics. The detection 
      limits under these conditions for As, Bi, Cd, Pb, Hg and Ti were 2.4, 4.08, 0.3, 
      2.1, 1.8, and 1.8 ng.mL-1, respectively. The relative standard deviations (RSDs) 
      were found to be less than 2.0%. For validation, a certified reference material 
      of NIST SRM 1570a spinach leaves was analyzed and the determined values were in 
      good agreement with the certified values. The recoveries for spiked samples were 
      found to be in the range of 89.6-104.4%.
