Adsorption Of Phenol From Aqueous Solution By Allium Sativum
نویسنده
چکیده
The adsorption studies of phenol from aqueous solution on allium sativum peel have been studied in the range of 50-250 mg/L initial phenol concentration .The study was carried out as function of contact time, pH, initial phenol concentration,allium sativum Linn peel dosage and temperature. The experiment demonstrated the maximum phenol was obtained at in pH of 2 and it takes 6h to attain equilibrium .The adsorption data was analyzed using the Langmuir and Freundlich isotherm models and it was found that Langmuir isotherm model represented the measured sorption data well. Batch adsorption models based on the assumption of the pseudofirst order and pseudo-second order mechanism were applied to examine the kinetics of the adsorption. The results showed that kinetic data were followed more closely the pseudo-second order model than the pseudo-first order

Background and purpose: Phenol is an organic pollutant that is found in industrial effluents and is very toxic to human and the environment. The purpose of this study was to use the ostrich feathers ash as a natural absorbent to remove phenol from aqueous solution. Materials and methods: For this study, ostrich feather ash was used as a new adsorbent in removal of phenol at different doses...

Leaf extracts of Cymbopogon citratus (lemon grass) and bulb extracts of Allium sativum (garlic) extracted with various solvents (ethanol, ethyl acetate and aqueous for Cymbopogon citratus, and ethyl acetate chloroform and aqueous for Allium sativum) were evaluated for antidermatophytic activity against Microsporum spp. isolated from different water samples. Out of a total of 60 water samples an...

Objective: One of the major clinical problems is the resistance of Candida speciestowards most of antifungals. The search for new antifungal drug from plants have helped to overcome this problem. This study evaluated the effects of Allium hirtifolium and Allium sativumextracts on Candida tropicalis both in vitro and in a mouse model of systemic candidiasis. Materials and Methods: In this study,...
