## Abstract
Abstract Analyze the decrease of the concentration of heavy metals Hg 2 +on entisols polluted by mercury due to the provision of humic acid and fulvic acid of Tithonia diversifolia. There are nine levels: With no humic acid and fulvic acid treatments (FVA0); 50 ml of fulvic acid per kg -1 soil (FA50), 75 ml (FA75),100 ml (FA100), 125 ml (FA125), 50 ml of humic acid per kg - 1 soil (HA50), 75 ml (HA75), 100 ml (HA100), and 125 ml (HA125). The concentration of Hg 2 +in entisol was measured by means of Mercury Analyzer (AAS). The results revealed that regarding mercury content in the soil, fulvic acid had a better effect on the change of Hg- chelate compared with humic acid. Fulvic acid was able to increase Hg-chelate up to 96.58%, whereas humic acid by 83.06% at a dose of 125 ml kg -1 entisols for 40 days of incubation.
