The aim of the present work was to investigate the feasibility of Kattamanakku tree leaf powder carbon (KTC) for Acid Red-114 (AR-114) adsorption. The adsorption of AR-114 on KTC material was studied as a function of KTC dose (0.05-1.20g). , solution pH 3-10, contact time and initial concentration (70-380 mg/l)., The influence of these parameters on the adsorption capacity was studied using the...

The potential use of Croatian natural zeolite clinoptilolite as alternative adsorbents for removal of enrofloxacin (ENRO) as model pollutant was studied in a batch system. The influence of contact time and initial ENRO concentration on the sorption process was investigated. The percentage removal of ENRO from aqueous phase decreased with an increase in initial concentration. The experimental da...

Titanium dioxide nanoparticles surface-modified by 5-sulfosalicylic acid 5-SA-TiO2 were prepared in ethanol by the chemisorption process. The effects of surface improvement on the photocatalytic degradation and adsorption of methyl orange MO were studied in a batch system by considering the various parameters, such as contact time, adsorbent dosage, pH, initial dye concentration and temperature...

  Background & Aims of the Study: Dyes are one of the most hazardous materials in various industries which can problems in health human, environment and ecosystem. The purpose of this study is the removal of Acid Orange 25 (AO25) diazo dye in aqueous solutions by adsorption onto clinoptilolite (CP) zeolite: study kinetic and isotherm model: experimental design and optimization. ...

ABSTRACT Introduction: Due to environmental and human health concerns related to humic acid (HA), mainly leading to disinfection by-products creation, removal or reduction of this matters is a necessary for drinking water suppliers. Based on resistive economy map road and move to self-sufficiency, it is necessary to produce our need in water treatment industry. One of the main co...

This paper investigates the potential of nano zero valent iron impregnated cashew nut shell nanoparticles (NZVI-CNS) as an effective adsorbent for the removal of phenol from aqueous solution. The effect of initial pH, adsorbent dosage, contact time and temperature were determined by batch adsorption experiments. Langmuir and Freundlich adsorption isotherm models were applied to the adsorption e...

Arsenic, one of the most toxic and dangerous elements in the environment affecting millions of people around the world, is associated with several diseases. In this pilot study, we investigated removal of arsenate from aqueous solutions using chitosan under the influences of initial arsenic ion concentrations, pH, contact time, and adsorbent dosages of chitosan. In order to assess the sorption ...

In this study, carbon was easily made from walnut wood as a low-cost and non-toxic natural adsorbent. Ziziphusspina-christi (ZSAC), an excellent adsorbent, were successfully synthesized by an in chemical vapor deposition method and used for the removal of Bismark Brown(BB) dye from aqueous solution. The as-synthesized Ziziphusspina-christi (ZSAC) were characterized by FT-IR technique. Various o...
