Webcarbon, fly ash, clay and red mud can be used. The process of biosorption can only be economical if a suitable eluant is used for the recovery of metals from the loaded adsorbent. ... functionalized silica gel as adsorbent for copper ion adsorption. J. Environ. Sei. {China), 2009, 21(11), 1473-1479. 15. WebThe simulation results illustrate that ion doping can significantly reduce the amount of CH4 adsorbed by kaolinite, but the type of doped ions has little effect on the amount of adsorption. The specific surface area of kaolinite and the interaction energy between CH4 and the kaolinite’s surface are two key factors that can determine CH4 adsorption …

Web5 jul. 2024 · There are two types of clays: (1) the silicate clays have characteristics of temperate regions and (2) the Fe 3+ and Al 3+ oxide and hydro oxides clays. These are better known in old soils of the tropics and sub-tropics [5]. Because of their small size soil colloids have a large surface area per unit mass and its volume ratio [7]. Web2 dagen geleden · In general, the size of clay minerals is an important factor in controlling of P adsorption, while the effects of nanosized clay in P immobilization is ignored.
