  • Study of the kinetics and the adsorption isotherm of cadmium(II) from aqueous solution using green algae (Ulva lactuca) biomass

    Batch experiments were conducted to study the adsorption of hazardous cadmium onto low-cost algae biomass in aqueous solution with respect to concentration of adsorbate, adsorbent dosage, contact time, solution pH and temperature. Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms and the isotherm constants were determined. The activation energy of ...

  • Cr(III) uptake by marine algal biomass: equilibrium and kinetics

    In this work, biosorption of Cr(III) by the marine brown algae Sargassum muticum was studied in a batch system. Kinetics and equilibrium experiments were conducted at different pH. Equilibrium data are well described by the Langmuir and Langmuir-Freundlich isotherms. The two mass transfer models give comparable results, but they did not provide a perfect representation of the sorption data. ...

  • Biosorption of methylene blue by nonliving biomass of the brown macroalga Sargassum hemiphyllum

    The ability of Sargassum hemiphyllum to remove methylene blue (MB) from aqueous solution was evaluated. Batch experiments were conducted to examine the effects of parameters such as initial pH, contact time, biomass dose and initial dye concentration on adsorption capacity. S. hemiphyllum before and after MB adsorption was characterized by Fourier transform infrared ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment

    Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

  • Old and new knowledge combine to protect Fiji`s fish

    Efforts to protect precious marine biodiversity by combining science and local knowledge are difficult but can work, reports Naomi Antony. Along the coastline of Fiji, threatened fishing communities have been combining the ancient and the new in their fight to conserve precious marine resources. Together with traditions remembered from centuries ago and community approaches ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...
