| Abstract: |
The economic’s development also bring urbanization and industrialization in many countries. However, many pollutants are also discharged into the environment, especially heavy metals (Zinc) seriously affects people's life and health as well as the water environment. This study reports on the preparation of activated carbon materials modified with HNO3 from Cassia Fistula seed for heavy metal removal. The results showed that zinc removal efficiencies were 65.06%; 72.19%; 75.64%; 78.57% corresponds to concentrations of 50, 30, 20, 10 ppm at optimal survey conditions pH 5, dosage of 0.3 g/50ml and 60 minutes processing time. The research results show that the activated carbon modified with HNO3 from Cassia Fistula seed is a promising absorption material for heavy metal removal in wastewater. |
