In this work, a KMnO 4 -modified-biochar-based composite material with manganese oxide produced at 600 °C was fabricated to investigate the sorption mechanism of Cd (II) and to comprehensively evaluate the effect of the modification on biochar properties. Cd (II) adsorption mechanisms were mainly controlled by interaction with minerals, complexation with oxygen-containing functional groups, and …

manganese-modified biochar for highly efficient sorption

In this study, corn stalk was modified by manganese (Mn) before (MBC1) and after (MBC2) pyrolysis at different temperatures (400~600 °C) under anaerobic conditions for Cd sorption in both water and soil. Batch experiments in aqueous solution were conducted to evaluate the optimum sorption capability by biochar with and without manganese-modified

Oct 01, 2020 · A new calcium-modified and starch-stabilized ferromanganese binary oxide (Ca-SFMBO) sorbent was fabricated with different Ca concentrations for the adsorption of arsenic (As) and cadmium (Cd) in water. The maximum As(III) and Cd(II) adsorption capacities of 1% Ca-SFMBO were 156.25 mg/g and 107.53 mg/g respectively in single-adsorption systems

Oct 01, 2001 · Diatomite and manganese oxides modified diatomite are an effective adsorbents for removing lead ions from solution. The sorption capacity of diatomite and modified diatomite were 24 and 99 mg g −1 for lead ions, respectively. The high increase in sorption efficiency of Mn-diatomite was attributed to high negative surface charge on the modified surface

This demonstrated that monolayer adsorption played a major role in the As(V) adsorption and is consistent with similar modeling of As(V) adsorption using cerium oxide modified activated carbon . It can be known that the maximum adsorption capacity of MBC for As(V) is 89.97 mg/g through the Langmuir model(C 0 = 200 mg/L, pH = 7.0, T = 323 K)
