Optimum Value for Zinc Removal from Saponin-Based Soil Washing Across soils at Onyeama Dumpsite, Enugu State
High reduction in the size of available land for agriculture has been a major problem facing most farmers today. The adoption of available plant based surfactants is yet to gain attention in south eastern Nigeria. This study was conducted to ascertain the level of Zinc removal from heavy metal contaminated dumpsites. Soil samples (C1, C2 and C3) were collected from the dumpsite and taken to the laboratory for analytical procedure. Saponin was also extracted from siam weed to aid the process of batch experiment for the removal of Zinc from contaminated soil. The result of the study showed that the optimum value for Zinc removal with saponin for soils C1, C2 and C3 were 96%, 99% and 100% respectively. It is recommended that saponin from Siam weed be adopted for the removal of Zinc from contaminated soil.
