Abstract:A pot culture study was conducted to investigate the impact of applying humic acid functionalized bentonite (HA-B) on the uptake of heavy metals by spinach. When the soil was amended with 7.5 g kg-1 of humic acid intercalated bentonite, there was a significant improvement in plant growth. Specifically, plant growth increased by 180.7%, 212%, and 231% during the first, second, and third cuttings, respectively. Additionally, the concentration of metals in the spinach decreased substantially, with reductions of 6… Show more
