Bamboo charcoal conceivably has a higher enrichment capacity for heavy metal ions due to its microporos structure and large surface area. For the first time, the potential of bamboo charcoal to act as an adsorbent for the preconcentration of heavy metal ions in water samples was investigated. Cadmium and nickel were selected as the model analytes, and ICP-AES as the method for detection. Factors affecting the enrichment efficiency, such as the kind of eluent and its volume, flow rate, and pH were investigated and optimized. The limits of detection for cadmium and nickel are 0.3 and 0.5 ng mL-1, respectively. There is good linearity (RS≥0.9998) in the range from 1 to 200 ng mL-1. The relative standard deviations vary from 2.4 to 4.2% (n = 7). The method has been applied to the analysis of drinking water, and results indicate that bamboo charcoal has a large potential as a SPE adsorbent.
