Biochar can be used as an alternative and efficient adsorbent for organic and inorganic pollutants. Therefore, based on previous study in which, a biochar loaded with mixed metal oxides of iron, tin or titanium catalysts results as a by-product of levulinic esters synthesis from biomass carbohydrates, this paper aim was to test this residue as biochar for the retention of phosphate from water samples. The obtained adsorbents based on Fe2O3-SnO2 and Fe2O3-La2O3-TiO2 were characterized by FT-IR and TGA analyses. The...

Industrial processes are made obligatory in terms of quality, all under a price/quality ratio to the desired level for the products. Also, it is ob ligatory imposed that the activity to take place in conditions and to be s ubjected to the environmental management: respecting the legislation, to ensure specific conditions , a proper ventilation, noise protection and ergonomics in the field.
