Compared cadmium adsorption from biochar and magnetite biochar in water

Water safety is a prerequisite for sustainable global quantitative and qualitative development. Heavy metal pollution has become major problem in our environment, where traditional heavy processing techniques were unsuccessful expensive. In this study, biochar magnetite have been used as an efficient, low-cost, safe, environmentally friendly method removal such cadmium. The prepared from palm fronds then activated by sodium hydroxide before treatment with two concentrations (5 ppm 10 ppm) of cadmium the water. (BC) had positive effect on improving efficiency removing (II). percentage to remove was 98% when we added 0.5 g solution. On other hand, composite materials mixing at mole ratio (2:1) prepare magnetite-biochar (MBC). A property adding Fe3O4 biochar, which led activation effective aggregates significant improvement adsorption performance metals while increasing up 100%.
