Biodiesel Production from Azolla filiculoides (Water Fern)
Purpose: To assess the potential of Azolla filiculoides, total body collected from a rice farm in northern Iran as source for biodiesel production. Methods: Solvent extraction using Soxhlet apparatus with chloroform-methanol (2:1 v/v) solvent blend was used to obtain crude oil from freeze-dried the Azolla plant. Acid-catalyzed transesterification was used to convert fatty acids (FA), monoglycer...
متن کاملKinetic and equilibrium studies on the biosorption of reactive black 5 dye by Aspergillus foetidus.
An isolated fungus, Aspergillus foetidus had the ability to decolourize growth unsupportive medium containing 100 mg L(-1) of reactive black 5 (RB5) dye with >99% efficiency at acidic pH (2-3). Pre-treatment of fungal biomass by autoclaving or exposure to 0.1M sodium hydroxide facilitated more efficient uptake of dye as compared to untreated fungal biomass. Pre-equilibrium biosorption of RB5 dy...
متن کاملEffect of Azolla filiculoides on removal of reactive red 198 in aqueous solution
The textile dyes are considered as major environmental problems. The dyes can be removed by various methods. Therefore, this study aimed to evaluate the adsorption rate of Reactive Red 198 (RR198) from aqueous solution by activated Azolla filiculoides. This was an empirical-lab study. The Azolla was used as an adsorbent to remove Reactive Red 198 dye. The effect of various parameters was invest...
متن کاملAdsorption of Malachite Green Dye from Aqueous Solutions Using Roots of Azolla Filiculoides
Pollution of water resources by various pollutants is nowadays a global environmental issue. Among the different type of water pollutants, dye represents a major polluting group. In this study, Azolla filiculides roots have been used for adsorption of Malachite Green (MG), a cationic dyed from aqueous solution. In this study, effects of operating parameters such as initial concentration of dye ...
متن کاملExperimental and Kinetic Studies on Acid Red 88 Dye (AR88) Adsorption by Azolla filiculoides
The use of Azolla filiculoides (AF) for the removal of Acid Red 88 dye (AR88) from aqueous solutions at different contact times, temperatures, pH, adsorbent doses and initial dye concentration was investigated. The extent of dye removal decreased with increasing adsorbent dosage and AR88 concentration, also increased with increasing contact time and temperature. The adsorption isotherms are des...
