The paper is aim to discuss the dye wastewater treatment by sewage sludge-based adsorbent. The adsorbent derived from sewage sludge , which produced through phosphoric acid-microwave method, and commercial activated carbon (ACC) were tested in the process of the Reactive Light Yellow dye wastewater treatment. The effects of pH value, contact time and the adsorbents' amount on the adsorption efficiency...
The effect of temperature on adsorption of reactive blue 19 (RB19) by cross-linked chitosan/oil palm ash composite beads was investigated. Temperature studied from range 30 to 50??C. It was observed that the uptake of this dye increased with increasing in temperature. Results revealed that sorptions of reactive blue 19 (RB19) on cross-linked chitosan/oil palm ash composite beads was endotermic in...
Textile effluents are major industrial polluters. The present paper aims to investigate and develop low cost adsorption methods for color removal wastewater using waste materials raw (RP) and activated carbon (ACP) from plane tree yellow leaves as adsorbent. The method was applied for the removal of direct red 81 while the influence of various factors such as adsorbate concentration and pH were studied...
The walnut shell, an agricultural waste, has been activated and used as an adsorbent for the adsorption of Direct and Reactive dyes from aqueous solution. Using a batch adsorption technique with respect to initial concentration and temperature the effects of various experimental parameters have been investigated. Equilibrium isotherms were analyzed by Langmuir, Freundlich, Temkin and Dubinin-Radushkevich...
