Phytotoxicity, Adsorption, Uptake and Removal of Azo Dyes in Sunflowers

Abstract:

In order to explore decolorization mechanisms of sunflowers to different azo dyes, we made a mass balance on dye removal pathways. Though hydroponic experiment and desorption test, we measured and calculated the total removal ratio, the adsorption ratio and uptake ratio of dyes. Phytotoxicity of dyes to sunflowers also determined through normalized relative transpiration (NRT) and relative growth rate (RGR). The results showed that sunflowers can survive in 20, 40 and 80 mg/L Amido black (AB), Orange G (OG) and Methyl orange (MO). The average color removal ratio of AB, OG and MO in 15 days was 72.14%, 40.21% and 34.42%. The average adsorption ratio of AB, OG and MO was 3.36%, 4.74% and 22.49% respectively. The average uptake ratio of AB, OG and MO was 68.78 %, 35.46 % and 11.94 % respectively. It is concluded that the main pathway of removal of AB and OG by sunflowers is uptake and the main pathway of removal of MO by sunflowers is adsorption. The significant difference of the apparent TSCF of sunflower for AB, OG and MO showed that the removal ability of sunflower to azo dyes is related to the specific chemical and physical property of the dye.
