| Abstract: | A remarkable relationship between the biodegradability and t heir quantitative structure of quaternary cationic surfactants was found using t he term of topologic index.A model equation related the degradability and molec ular connection index was established by the regression analysis,which showed ex cellent complex related coefficient (R>0.97), standard deviation (E_0= 13.7910) and average standard deviation (D=0.0432). The values calculated by using above equation were in good agree with the values reported in literature for biodegradability of quaternary cationic surfactants .It indicated that the equation was reliable and was a new method for evaluatio n of biodegradability of quaternary cationic surfactants. |
