ETHYLENEDIAMINE TETRAACETIC ACID (EDTA) MODIFIED RICE HUSK AS AN ADSORBENT FOR DYES AND HEAVY METAL IONS REMOVAL Abstract: The potential of various chemically modified rice husk to remove Methylene Blue (MB) and Reactive Orange 16 (RO16) from aqueous solution
The potential of various chemically modified rice husk to remove Methylene Blue (MB) and Reactive Orange 16 (RO16) from aqueous solution was investigated. It was found that ethylenediamine tetraacetic acid modified rice husk (ERH) has the highest adsorption capacity for both MB and RO16. ERH was produced by treating natural rice husk (NRH) with 0.5 g of ethylenediamine tetraacetic acid (EDTA) i...
متن کاملCharacterization of H3PO4-Treated Rice Husk Adsorbent and Adsorption of Copper(II) from Aqueous Solution
Rice husk, a surplus agricultural byproduct, was applied to the sorption of copper from aqueous solutions. Chemical modifications by treating rice husk with H3PO4 increased the sorption ability of rice husk for Cu(II). This work investigated the sorption characteristics for Cu(II) and examined the optimum conditions of the sorption processes. The elemental compositions of native rice husk and H...

متن کاملCoal Ash as a Low Cost Adsorbent for the Removal of Xylenol Orange from Aqueous Solution
The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...
