Removal of direct blue 129 from aqueous medium using surfactant-modified zeolite: a neural network modeling
Background: Conserving water for human survival and providing future security are important issues that need to be addressed. Methods: In this study, a zeolite modified with hexadecyl trimethyl ammonium bromide (HDTMA-Br), a cationic surfactant, and its application in removing direct blue 129 (DB129) was examined. Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy...
متن کاملAdsorptive removal of Cu(II) from aqueous solution using modified rice husk
In this study, the modified rice husk was tested to remove Cu(II) from water. Batch experiments were carried out to evaluate the adsorption characteristics of the modified rice husk for Cu(II) removal from aqueous solutions. The adsorption isotherms, thermodynamic parameters, kinetics, pH effect, and desorbability were examined. The results show that the maximum adsorption capacity of the modif...
متن کاملAdsorptive removal of azide ion from aqueous solutions using modified activated carbon magnetic nanocomposite
In this work, the activated carbon/magnetic Fe3O4 nanocomposite was synthesized and characterized by TEM and XRD measurements. This magnetic nanocomposite was modified with cetylpyridinium chloride (CPC) and thus used as a new adsorbent for removal of azide ion from an aqueous solution. In an aqueous solution of azide ion, the adsorption capacity was evaluated using both the Langmuir and Freund...
متن کاملCationic surfactant modified wood sawdust for removal of acidic dyes
In this paper, application of sawdust prepared from Narra wood (SD) modified with cationic surfactant of cetyltrimethylammonium bromide (SD/CTAB) was used for removal of two typical acid dyes commercially named as Acid Green 25 (AG25) and Acid Red 14 (AR14) from aqueous solutions. The effects of experimental variables, such as pH, initial dye concentration, adsorbent dose, contact time and temp...
متن کاملEffective Parameters on Removal of Rhodamine B from Colored Wastewater by Nano polyaniline/Sawdust Composite
Background and purpose: Contamination of groundwater with colored and toxic wastewater causes many environmental problems and has adverse effects on human health. This study aimed at coating a nano polyaniline polymer layer on the surface of sawdust and preparing polyaniline sawdust composite (Pan/SD) via chemical polymerization of aniline monomer onto sawdust in aqueous solutions and removal o...
