| Abstract: |
| In this paper, continuous flowing method for leaching toxicity determination of cyanide in solid waste has been developed. The result indicated that linear curve was obtained in the range of 0-200 μg/L with a good linearity. The linear correlation coefficient could reach 0.9998 and the limit of detection was 0.327 μg/L. The precision is less than 2.6%, the recoveries of real samples is between 96-103%, the continuous flow injection method has good agreement with traditional GB method in determination of real sample. |
