1. Superfosfato triplo, lama vermelha e zeólitas para remediação de metais pesados em solo contaminado / Remediation of contaminated soil with heavy metal using triple superphosphate, red mud and zeolites
Due to the heavy metal persistence in soils, the contamination by these elements is considered permanent and might result in great impact causing a degradation of the chemical and biological properties of the soil. Stabilization techniques have been used as an efficient tool for the remediation of soils that are contaminated by heavy metals, and they show al
