Abstract
Pollution emanating from effluents containing residual dyes which are not biodegradable has become a serious environmental problem in the last decade due to the increasing and fast-growing usage of dyes in different applications. Even small amount of dye in water effects the aesthetic value and water transparency in water bodies therefore the contaminated dye in waste water needs to be removed before released to natural stream. The dye removal process which is the low cost of operation and occurred through the green reaction under the usage of the natural waste is the interested method. Biosorption is leaded to the decolorizing the waste water by using the agricultural waste through the adsorption technique. In this study the Malachite Green (MG) adsorption onto Plumeria obtusa leaf powder was investigated in terms of both adsorption efficiency and kinetic study. The effect of various parameters i.e. initial dye concentration, contact time, adsorbent dosage, pH and temperature were investigated. The adsorption data fitted the isotherm model such as Langmuir, Freundlich. Thermodynamic parameters (Such as ∆G0, ∆H0, ∆S0) were also determined to find out the spontaneity of the adsorption process.
