“…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.…”

Excessive phosphorus discharged into the environment could result in the eutrophication, leading to water pollution. Hence, the efficient method for phosphorus removal is urgently in need. In this paper, an agricultural by‐product, corn bract, modified by Zr was proposed to remove different forms of phosphorus. A comparison study about the adsorption performance of organic phosphorus (OP) and inorganic phosphorus (IP) was investigated. The results indicated that both the OP and IP reached the maximum adsorption amounts when the initial pH was 2. Compared with IP adsorption, the adsorbent showed higher adsorption rate but lower adsorption capacity for OP. The complexation and the electrostatic attraction were possibly the main adsorption mechanisms. Practitioner points The agricultural waste, corn bract, was proposed to remove phosphorus. The adsorption performances of OP and IP were compared. The adsorbent showed higher adsorption rate but lower adsorption capacity for OP.

“…From literatures, the adsorption isotherm of mixed metal ion solution have been reported. For example, the adsorption isotherm of mixed metal ions solutions (Ag(I), Cu(II), Fe(II), and Pb(II)) by an aminated polyacrylonitrile nanofiber mat using ICP technique was fitted with the Langmuir adsorption isotherm 42 . Therefore, the high sample throughput analytical process by using AAS or ICP is necessary for the selective adsorption of mixed metal ions study.…”

A bio -renewable polyisoprene obtained from Hevea Brasiliensis was used to produce functionalised carbon composite foam as an adsorbent for heavy metal ions. Functionalised carbon materials (C-SO3H, C-COOH, or C-NH2) derived from coconut shell waste were prepared via a hydrothermal treatment. Scanning electron microscopy images showed that the functionalised carbon particles had spherical shapes with rough surfaces. X-ray photoelectron spectroscopy confirmed that the functional groups were successfully functionalised over the carbon surface. The foaming process allowed for the addition of carbon (up to seven parts per hundred of rubber) to the high ammonia natural rubber latex. The composite foams had open pore structures with good dispersion of the functionalised carbon. The foam performance on copper ion adsorption has been investigated with regard to their functional group and adsorption conditions. The carbon foams achieved maximum Cu(II) adsorption at 56.5 $${\text{mg g}}_{\text{foam}}^{-1}$$ mg g foam - 1 for C-SO3H, 55.7 $${\text{mg g}}_{\text{foam}}^{-1}$$ mg g foam - 1 for C-COOH, and 41.9 $${\text{mg g}}_{\text{foam}}^{-1}$$ mg g foam - 1 for C-NH2, and the adsorption behaviour followed a pseudo-second order kinetics model.
