Adsorption Study With Different Eco-Friendly Activated Carbons For The Removal Of Basic Dye From Aqueous Solution

Abstract

 A carbonaceous adsorbent prepared from plant material like Acacia Arabic Bark Carbon (AABC) was found to show good porosity, appreciable surface area and consequently adsorbs dyes to an appreciable extent. Effect of various experimental parameters have been investigated using batch adsorption technique at room temperature (30±1°C) and the adsorption of Rhodamine B (RB) on carbonaceous adsorbent confirms to Langmuir equation, is a first-order process and pore diffusion controlled. The efficiency of carbonaceous adsorbent was evaluated by comparing the results with those obtained on a Commercial Activated Carbon (CAC). These results indicate that AABC could be employed as low-cost adsorbent for the removal of cationic dye from industrial wastewater. This investigation suggested that natural adsorbents are from plant materials can be utilized as adsorbent, because of their appreciable extent removal of dyes. FT-IR spectra of the adsorbents were recorded to explore the number and position of functional groups available for the binding of dye onto adsorbents. SEMs of the native and exhausted (CAC and AABC) were recorded to explore the morphology of the adsorbent.
