Screening the functions of modified rice straw biochar for adsorbing manganese from drinking water

Abstract

Modified biochar was used to remove Mn2+ from water with principal adsorption functions of precipitation and cation exchange. The MnCO3 and Al–Si–O–Mn mainly driven precipitation and Na+, Mg2+ and Ca2+ primarily contributed to the cation exchange.

Remediation of Cadmium and Lead in Mine Soil by Ameliorants and Its Impact on Maize (Zea mays L.) Cultivation

“…[15][16][17][18]. Biochar can be obtained from various sources, such as through the high-temperature pyrolysis of plants or agriculture, to achieve effective utilization of waste resources [16][17][18][19]. Due to the low cost of raw materials used in the production of biochar, and its excellent pollutant removal properties, it is an economically and environmentally friendly material that has attracted attention in the scientific community.…”

Efficient adsorption and separation of Mn–Cu–Cd composite pollutants using MOF-based calcium alginate composite hydrogels

“…10 Among them, the adsorption method is commonly employed in environmental treatment owing to its selectivity, low cost, and high efficiency for target ions. 11 However, existing Mn removal materials, such as diatomite, 12 biochar, 13 and MgAl-LDHs, 14 have limited adsorption capacity for Mn, with unit adsorption capacities of 20.65 mg g −1 , 28.37 mg g −1 , and 91.85 mg g −1 , respectively. Furthermore, the majority of existing treatment studies have mostly concentrated on single Mn 2+ pollution, with little study focusing on the treatment of Mn composite pollution.…”

Kinetic and Thermodynamic Analysis of the Adsorption of Methylene Blue onto Biochar

“…In recent years, biochar has become an attractive method for removing organic molecules and metals from contaminated water by adsorbing the pollutants to its surface. ,,− Biochar is made by the pyrolysis of various biomass materials, such as lumber byproducts, straw, and sludge byproducts from water treatments. Its properties and adsorption capacity toward specific contaminants depend on several parameters in the creation of the biochar and the environment in which adsorption occurs .…”
