| Abstract: | The Pseudomonas aeruginosa NPA-5 with high degradation of naphthalene was isolated from the soil contaminated by coke plant waster.The adsorption characteristics and bioadsortpion kinetics of naphthalene in the biological activated carbon(BAC) system were investigated.The results show that the adsorption of naphthalene by activated carbon particles is efficient with the adsorption isotherms conforming to with Langmuir and Freundlich models.The NPA-5-loaded BAC has high biodegradation efficiency of naphthale... |
