Investigation of organic and phosphate amendments in remediate heavy metal in polluted soil
Abstract
This study was held out on by bioremediation technique to remediate heavy metal that is
from Harum Manis farms. This research is conducted in conjunction to examine the
effectiveness of organic and phosphate amendments in bioremediation of heavy metal in contaminate soil and to compare the different amount of amendments with the
degradation of the contaminant. The biostimulation technique is used to remediate the contaminated soil. Biostimulation technique emphasis on nutrient content that affecting
the degradation of heavy metal. The amendment usage of organic amendment is wood
sawdust while for the phosphate amendment is phosphate fertilizer. Both of the
amendments shows a great change in degradation of heavy metal. The result shows the
mixture of wood sawdust and phosphate fertilizer is more efficient in the Fe degradation
by 74.96%. Next, it followed by the usage of wood sawdust and phosphate fertilizer
with 73.59% and 72.26% respectively. The potential of ferum degradation is higher than
the zinc degradation.
