Study of phenol adsorption from wastewater using pumice modified by Mg/Cu bimetallic particles

Background and Aims: The major sources of phenol pollution in the aquatic environment are wastewaters from dyeing, pesticide, polymeric resins, petroleum and petrochemicals industries. Introducing phenolic compounds into the environment especially water bodies are one of the most important issues due to their toxicity for human and aquatic organisms. The aim of this work was to assess the capability of pumice- bimetal particles as an adsorbent for phenol removal from wastewater.Materials and Methods: In this experimental study, the pumice volcanic stone that was provided from the Kurdistan province was used. The pumice particles (mesh 30) were modified by metals of magnesium and copper, as bimetal compound. The functional groups and specific surface area of pumice-bimetal particles were determined. After the preparation of a synthetic wastewater contain phenol, the influences of parameters including wastewater pH (2–12), reaction time (3–60 min), initial phenol concentration (25- 150 mg/L), and the adsorbent dose (0.5–2.5 mg/L) were investigated. The phenol concentration was measured using photometric method. Adsorption isotherm was evaluated using Freundlich and Langmuir models.Results: The specific surface area, total pore volume, and mean pore diameter were determined to 4.67 m2/g, 0.0046 m3/g, and 48.23 nm, respectively. Results showed that the pumice-bimetal exhibited the best performance for phenol removal (97.3%) at dose 2 mg/L, pH 8, and contact time 30 min. The equilibrium data fitted well with the Freundlich model (R2= 0.985).Conclusions: According to results, the pumice-bimetal particles are an efficient adsorbent and promising option for eliminating various concentrations of phenol from water and wastewater.Key words: Adsorption, Isotherm, Phenol, Pumice-bimetal, Wastewate

Abatement of Azo Dye from Wastewater Using Bimetal-Chitosan

We introduce a new adsorbent, bimetallic chitosan particle (BCP) that is successfully synthesized and applied to remove the orange II dye from wastewater. The effects of pH, BCP quantity, and contact time are initially verified on the basis of the percentage of orange II removed from the wastewater. Experimental data reveal that the Cu/Mg bimetal and chitosan have a synergistic effect on the adsorption process of the adsorbate, where the dye adsorption by Cu/Mg bimetal, chitosan alone, and bimetal-chitosan is 10, 49, and 99.5%, respectively. The time required for the complete decolorization of orange II by 1mg/L of BCP is 10 min. The Langmuir model is the best fit for the experimental data, which attains a maximum adsorption capacity of 384.6mg/g.The consideration of the kinetic behavior indicates that the adsorption of orange II onto the BCP fits best with the pseudo-second-order and Elovich models. Further, the simulated azo dye wastewater can be effectively treated using a relatively low quantity of the adsorbent, 1 mg/L, within a short reaction time of 20 min. Overall, the use of BCP can be considered a promising method for eliminating the azo dye from wastewater effectively

High potential for the formation of haloacetic acids in the Karoon River water in Iran

The impact of the total organic carbon (TOC), chlorine dosage, water temperature, reaction time, pH, and seasonal variation on the formation of haloacetic acids (HAAs) in the Karoon River in Iran was studied. The results showed that dichloroacetic acid and trichloroacetic acid were the most detected HAA5. The HAA5 formation potential (HAA5FP) levels in the Karoon River water in spring time, when the water TOC content exceeded 4 mg/L, were 1.38 times higher than during the winter season, when the water TOC content was below 3.5 mg/L. There was not a strong correlation between the HAA5FP and the residence time for the Karoon River water. For the rang
