Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.

Fourteen cadmium-tolerant strains were isolated from the Beijing coking plant soil which cadmium content exceeds the standard. The 16SrDNA sequence analysis showed that Pseudomonas aeruginosa take the percentage of 72% and is the dominant microorganisms. These strains were further used to study the adsorption efficiency to Cd2+ and Pb2+. Among these strains, two cadmium-tolerant strains labeled as Z11 and Z13 have good adsorption efficiency to Cd2+ and Pb2+ were screened. Effects of pH and temperature on the growth of the strains Z11 and Z13 was studied and drew the growth curve of the strains under the optimal growing conditions. The results showed that the optimum growth temperature of the two strains were 20 to 25°C, both of them can´t tolerate high temperature. The optimum growth pH of the strain Z11and Z13 were respectively 7 to 9 and 5 to 7.
