Adsorption Efficiency of Acid Brown 43 and Reactive Yellow 2 onto Green House Gas Emitting Agro Waste obtained from Epiphyllum Oxypetalum (Cactaceae)
J. Environ. Nanotechnol., Volume 5, No 1 (2016) pp. 01-07
Abstract
Epiphyllum oxypetalum is a species of cactus and one of the most commonly grown of the Epiphyllum species. It is one of the under-utilized resources available in the tropical regions of the globe and can be used as a substitute for digitalis. The Shoshone Indian tribe calls the night blooming Cereus "Pain in the heart" and used it for heart pain. Scanty work was reported on the phytochemical properties of leaf extract. No documented research work was reported on its leaf and flower for assessment of adsorption studies. Thus the present investigation was carried out to access the adsorptive studies of plant wastes. The activated carbon was prepared from Epiphyllum oxypetallum wastes by ZnCl2 activation. The adsorption kinetics of Industrial dyes was studied from the activated carbon. The optimum temperature was found to be 300 °C and the adsorption data fitted well onto Langmuir adsorption isotherm model. The high surface area of activated carbons was demonstrated to be promising adsorbents for pollution control and for other applications.
