The present study analyzed the efficiency of a naturally derived fenugreek powder for removal of Congo red dye from the aqueous solution. The flocculation Studies on Congo Red (CR) a hazardous, textile dye onto Fenugreek Powder and its adsorption was analyzed. Fenugreek Powder is Eco-friendly, biodegradable and locally available in the market. The dye adsorption process was performed in different batches at varying pH, dye concentration, adsorbent concentration and contact time to get the best results. The result showed that the maximum removal of dye was 42.4% with 10mg/l of Fenugreek powder at pH 4.

Uptake Process

This study evaluated the potential application of a biomass material, corncob lignocellulose (CL), as a novel adsorbent for the removal of basic dyes from aqueous solutions. The adsorption behavior and mechanism of basic dyes on CL was investigated via batch experiments. Both adsorption and desorption studies showed that the attachment of basic dyes onto CL was ascribed to a combined interaction involving electrostatic attraction and chemisorption. The decolorization efficiency of CL increased with increasing solution pH and temperature. Thermodynamic parameters demonstrated the spontaneous and endothermic nature of the adsorption. The dye uptake process was best described by the Langmuir isotherm. The adsorption capacity of CL for Methylene blue, Crystal Violet and Malachite Green at 30°C was calculated to be 145.8, 121.8 and 65.7 mg/g, respectively.

This study presents the preparation of corncob-based bio-char and its application in adsorptive removal of three basic dyes (methylene blue, crystal violet and basic fuchsin) from aqueous solution. The adsorption behavior of basic dyes on bio-char was investigated via batch experiments. Experimental results showed that the adsorption efficiency of bio-char increased with increasing solution pH and temperature. Thermodynamic parameters demonstrated the spontaneous and endothermic nature of the adsorption. The dye removal process fitted the Langmuir isotherm well. The adsorption capacity of bio-char for methylene blue, crystal Violet and basic fuchsin at 25°C was calculated to be 126.58, 81.96 and 75.18 mg/g, respectively.
