The results showed that a low concentration of Triton X-100 simultaneously promoted the sorption capacity of the biochar and the degradation activity of <i>P. aeruginosa</i>, thereby significantly enhancing the removal of acenaphthene from water by the immobilized <i>P. aeruginosa</i> material. Compared with the control without Triton X-100, a low concentration of Triton X-100 significantly increased the acenaphthene removal rate by 20-50%. The optimal conditions for preparing the TFBIP were a loading time of 24 h, the usRSC advancesRemoval of acenaphthene from water by Triton X-100-facilitated biochar-immobilized <i>Pseudomonas aeruginosa</i>.PMC9081626413013274150152121407037Lu LHe SJi XLi AYang CfalseRemoval of acenaphthene from water by Triton X-100-facilitated biochar-immobilized <i>Pseudomonas aeruginosa</i>.By adding the nonionic surfactant Triton X-100 and using biochar as an immobilization carrier, a Triton X-100-facilitated biochar-immobilized <i>Pseudomonas aeruginosa</i> (TFBIP) material was prepared using the sorption method and was used to treat acenaphthene in water.
