“…These parameters and correlation coefficients ( R 2 ) were listed in Table . The correlation coefficients of pseudo‐second‐order kinetics were obviously better than those of pseudo‐first‐order kinetics, indicating that the adsorption reactions followed pseudo‐second‐order kinetics, and suggesting that the adsorption may be chemisorption (Ho & Mckay, ; Li, Wang, Xiao, & Zhang, ; Li, Liang, et al., ; Liao, Ding, Wang, & Shi, ). For phosphorus uptake, the calculated adsorption capacities of OP and IP were 12.48 mg/g and 15.98 mg/g, respectively, which were in good agreements with the measured data.…”
