In the algorithm,an idea that all maximum independent sets are formed straightway by deleting experiment is put forward and realized,that condition of maximum independent is satisfied gradually by doing time after time delete experiments.

In the closed circle DNA algorithm,an idea that complementary sets of vertex covering are formed straightway by delete experiment is put forward and realized,which has design of the algorithm inimitable and novel.

To realize filtering algorithm of SAT problem using DNA computing model,the data structure of 2n dimension vector is adopted to do DNA encoding,which represents a valuation of SAT problem,and delete experiment of closed circle DNA computing model can just complete selection of initial valuations to obtain feasible solutions of SAT problem.

The object of the paper is MC-LR, the research was carried out successfully which included analytical method, extraction and purification, identification and the removal experiment with UV、O3 and UV/O3 three techniques.
