Adsorption of Lead ions from aqueous solution by the dead biomass of nanoalgae Scenedesmus sp.
In attempts to remove toxic metal lead, distinct types of algae biomass have been scrutinized as alternatives to conventional physicochemical technologies. In this research, the absorption of Lead by nanoalgae Scenedesmus sp. was studied at concentration of10 to 100 mg/L, pH 3 to 8, temperature 15 to 40 °C and exposure time of 10 to 60 minutes)in a batch culture system. The concentration of Le...
متن کامل“Rational” Management of Dichlorophenols Biodegradation by the Microalga Scenedesmus obliquus
The microalga Scenedesmus obliquus exhibited the ability to biodegrade dichlorophenols (dcps) under specific autotrophic and mixotrophic conditions. According to their biodegradability, the dichlorophenols used can be separated into three distinct groups. Group I (2,4-dcp and 2,6 dcp - no meta-substitution) consisted of quite easily degraded dichlorophenols, since both chloride substituents are...
متن کاملIons from Aqueous Solutions by Biosorption Processes
Due to the disadvantages of heavy metal removal from aqueous sytems by conventional methods, alternative new methods have been investigated lately. Biosorption is one of these new methods. In this method, metal ions are transported into cell structure, and removal is ensured by several mechanisms that occured between living or non-living microorganisms and metal ions. The metal removal, the use...
متن کاملbiosorption of cr (vi) ions from aqueous solution by the dead fungal biomass aspergillus niger
chromium is one of the major causes of environmental pollution. to remove heavy metal ions from water, microorganisms can be used. in this study, dead fungal biomass of aspergillus niger is used. the biomass was boiled in 0.5 n naoh solutions to increase the metal removal capacity of a.niger and was applied when the ph of wash solution was in the normal range. the optimum adsorption ph value ob...
متن کاملWaste utilization and biodiesel production by the green microalga Scenedesmus obliquus.
Scenedesmus obliquus was cultivated in three types of waste discharges to couple waste treatment with biodiesel production. The lipid pool accumulation was boosted to 1.0 g liter(-1) against 0.1 g liter(-1) for the control. The waste-grown S. obliquus showed an increase in the content of the saturated fatty acid pool, which is desirable for good-quality biodiesel.
