Adsorption Equilibria of Cadmium on Algal Biomass

Gasification of Phycoremediation Algal Biomass

Microalgae have been utilized in wastewater treatment strategies in various contexts. Uncontrolled algal species are a cheap and effective remediation strategy. This study investigates the thermochemical potential of wastewater treatment algae (phycoremediation) as a means to produce renewable fuel streams and bio-products. Three gasification temperature levels were investigated in an auger gas...

Algal Biomass and Biodiesel Production

Adsorption behavior of cadmium on modified mesoporous aluminosilicates

In this study, mesoporous MCM-41 has been modified by incorporation of aluminum ion asa rapid, simple and inexpensive method for modification. The adsorbent is characterized usingpowder X-ray diffraction and nitrogen adsorption-desorption isotherm data. The distributioncoefficient of cadmium ion on the mesoporous aluminosilicates has been enhanced with theincrease of the aluminum in the framewo...

Biosorption of diesel and lubricating oil on algal biomass

Algae are widely used as biosorbent for the sorption of heavy metals, however sorption of oil on algae has not been explored. Algae in marine and fresh water environment may affect the fate and transport of spilled oil. Sorption of diesel and lubricating oil was studied using dead biomass of Spirulina sp. and Scenedesmus abundans. The rate and extent of sorption was studied in well mixed batch ...

Algal-urchin biomass responses following mass mortality

A mass mortality occurred in 1983, killing 95-99% of the Diadema antillarum Philippi in the Caribbean. This study, conducted in Lameshur Bay, Saint John, U.S. Virgin Islands, reports the impact of the mass mortality on Diadema population density, algal biomass, and Diadema body size. Census dates were 6 months before and 6, 12, 18, 26, 30, and 42 months after the mass mortality. There was an in...
