Abstract:Andisol has a large surface area, is mesoporous, and contains the active groups' silanol (Si-OH) and aluminol (Al-OH). Besides andisol, cellulose is a good adsorbent, because microcrystalline cellulose has an active hydroxyl group (OH). The number of active adsorbent groups can be enhanced by chemically modifying the surface area (increment), or adding other materials. These modifications included alkaline modified-andisol with the addition of NaOH to increase pore size, cellulose hydrolysis with HCl to increa… Show more
