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