Degradation kinetics of cypermethrin with immobilized culture.

Treatment Regression Equation k (day−1) R 2 t1/2 (days)
MSM + SA ln(Ct/Co) = –0.0131x + 4.5868 0.0131 0.933 52.9
MSM + SA + SG4 ln(Ct/Co) = –0.1336x + 4.7126 0.133 0.966 5.3
MSM + AD ln(Ct/Co) = –0.0136x + 4.5732 0.0136 0.859 50.9
MSM + AD + SG4 ln(Ct/Co) = –0.1089x + 4.6867 0.1089 0.977 6.4

Initial cypermethrin concentration was 50 mg·L−1. A linear equation was derived from chemical data of C0 and Ct, to calculate k, R2, and t1/2 values. SA: sodium alginate; AD: agar discs.
