An agricultural detritus bagasse fly ash (BFA) is a good source of silica and alumina which can be converted into zeolitic material by hydrothermal synthesis using conventional, microwave and fusion techniques. Zeolites derived from these techniques can also be modified by electrolytic media, surfactant, magnetite treatment and the ratio (Si/Al) adjustment to achieve enhanced properties for sorption study. Zeolite is an aluminosilicate compound with different structures and sizes. It has the best application in adsorption by the seizure of pollutants from the industrial effluent. It also has wide applications in catalytic activity in various syntheses. The bagasse fly ash and its derivatives are used for the removal of organic and inorganic contaminants in optimized conditions of adsorption such as pH, time, dose, concentration and temperature. Pollutants like phenols, dyes, pesticides, heavy metals and inorganic anions are successfully minimized from waste water using these bagasse fly ash zeolite composites.
