摘要: Abstract Although phytoremediation is a promising method for the removal of cadmium (Cd) from contaminated soil, plants remove Cd soil slowly. To increase uptake by plants, effects application chloride ions (Cl−) and decrease in pH on amount taken up were investigated pot experiment using collected paddy fields with mining wastewater. Three treatments applied (all quantities expressed 350 g basis): control (0.6 g (NH4)2SO4 as N fertilizer), Cl− (0.5 g NH4Cl fertilizer 0.15 g CaCl2) low (0.8 g powdered sulfur plus CaCl2). Sunflower (Helianthus annuus), kenaf (Hibiscus cannabinus) sorghum (Sorghum vulgare) grown treated 33 days growth chamber under 26°C/24°C day/night (16 h/8 h) regime. At harvest, separated into roots, stems leaves, concentration was determined. The approximatel...
