existence of acid humic in water resources is undesirable and causes carcinogenic component in disinfection process due to reaction with chlorine. due to their cost-effectiveness and higher physical resistance than activated carbon, natural zeloites are used for removing various pollutants. . in the present study, iranian natural zeolite modified with cetylpyridinium bromide (cpb) was investiga...

The adsorption of Triton X-100 in aqueous solution on the granite sand has been investigated to evaluate its ability as an adsorbent. Various parameters such as agitation time, adsorbent dose, adsorbent size, initial concentration of adsorbate, pH, temperature, and effect of interference ions were studied on the laboratory scale to establish optimum conditions for the removal of TX-100 from the...

Animal bone charcoal (ABC) produced from animal bones was used as adsorbent to remove Cr(VI) from its aqueous solution . Labority experimental investigation was carried out to identify the effect of contact of time, pH, adsorbent dose and initial concentration on the adsorption of chromium from metal solution. Results showed that pH 2 was the most suitable, while the removal of Cr(VI) ions with...

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...

A variety of adsorbents are available naturallyrice husk, neem bark, clays etc. that can be used to remove dye from the discharged waste. In this study,the use of lowcost, locally available, eco-friendly and highly efficient adsorbent has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. The removal of the textile dye Methylene blue (MB...

Adsorption studies were conducted to determine whether adsorbent concentration (soil-solution ratio) affected insecticide adsorption by soils and clays. Adsorption isotherms were obtained for several insecticides in Bondhead sandy loam and Ca-saturated illite suspensions using adsorbent concentrations that were varied over several orders of magnitude. There was no evidence that altering adsorbe...
