12 13 The removal of fluoride using red mud has been improved by acidifying red mud with 14 hydrochloric, nitric and sulphuric acid. This investigation shows that the removal of fluoride 15 using red mud is significantly improved if red mud is initially acidified. The acidification of 16 red mud causes sodalite and cancrinite phases to dissociate, confirmed by the release of 17 sodium and alumi...

The removal of color from synthetic wastewater containing Congo red was experimentally investigated using electrocoagulation process. The effects of operational parameters such as current density, electrolysis time, electrolyte concentration, electrode distance, initial dye concentration, initial pH and temperature on color removal efficiency were investigated in this study. The tentative resul...

Abstract Aspergillus parasiticus (A. parasiticus) CBS 100926T was used as a biosorbent for the removal of Methylene Blue (MB), Congo Red (CR), Sudan Black (SB), Malachite Green Oxalate (MGO), Basic Fuchsin (BF) and Phenol (PR) from aqueous solutions. The batch biosorption studies were carried out function dye concentration contact time. process followed pseudo-first-order pseudo-second-order ki...

Background & Aims of the Study: Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim of this study was to evaluate the performance of H2O2 and H2O2/Fe0 Iron in removal of dye Acid Red 18 from aque...

In this work, removal of C. I. Acid Red 14 was investigated by Pumice stone as a low cost adsorbent. Various parameters such as initial dye solution, contact time and pH were studied. Removal of dye were increased by increasing of contact time and initial dye solution and deceased by increasing of pH. Three isotherm models were studied. Linear and non-linear regression analyses were used fo...

Contamination of water resources with petroleum products is a serious environmental problem. The current study was carried out to investigate the effect of using raw and heat activated red mud (RM) as adsorbent to remove insoluble fraction of gasoline from aqueous solution. Some parameters such as pH, contact time, adsorbent dose and initial concentration were optimized in adsorption process to...
