Biosorption of Rhodamine B and Malachite green from aqueous solutions by Tamarindus indica fruit shells
The removal of rhodamine B and malachite green from aqueous solutions was studied in batch adsorption systems using Tamarindus Indica fruit shells as sorbents. The well known Freundlich, Langmuir and Redlich-Peterson isotherm equations were applied to the equilibrium sorption data obtained. The sorption dynamics were found to obey the pseudo-second order rate equation and particle diffusions ap...
متن کاملRemoval of Methylene Blue, Malachite Green and Rhodamine B in a Ternary System by Pistachio Hull; Application of Wavelet Neural Network Modeling and Doehlert Design
Most of previous papers in the field of dye removal used one dye or dyes with nearly separate spectra that simplifies dyes concentration determination by Beer's law at different λmax. In many real situations, dyes with highly overlapped spectra exist and their concentrations can be determined by multivariate analysis methods. In this study, principal component-wavelet neural network (PC-WNN) wa...
متن کاملOn different photodecomposition behaviors of rhodamine B on laponite and montmorillonite clay under visible light irradiation
ess as: P r visibl niversity 2013.11.0 Abstract In this study, laponite and montmorillonite clays were found to be able to decompose rhodamine B upon visible light irradiation (k > 420 nm). Very interestingly, it was found that rhodamine B on laponite underwent a stepwise N-deethylation and its decomposition was terminated once rhodamine 110, as a decomposition product, was formed, whereas the ...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
