Water pollution is increasing due to urbanization and industrialization. Waste water pollution raised concern because of its influence on plants and humans. Water hyacinth (Eichhornia crassipes) is used for the removal of pollutants because of its phytoremediation efficiency. In this study, water hyacinth (Eichhornia crassipes) has been tested for simultaneous elimination of phenol and cyanide from mono and binary component aqueous solution in batch systems. The plant was grown at six concentrations of phenol and cyanide in the ratio of (10:1), i.e. 100:10, 200:20, 300:30, 500:50, 700:70 and 1000:100 mg/L in aqueous solution. The effect of process parameters such as initial concentration of phenol and cyanide and pH was evaluated. The plant was found capable of eliminating up to 96.42% of phenol (300 mg/L) and 92.66% of cyanide (30 mg/L) during the 13 days cultivation time at pH 8. The calculated K_m of the root length elongation for phenol was 5.20 mm and the V_max was 12.52 μg phenol/g root/h. However, the calculated K_m of the root length elongation for cyanide was 0.39 mm and the V_max was 14.99 μg cyanide/ g root/h. In the Eichhornia crassipes plant, the biochemical parameters such as chlorophyll, protein and sugar content have been indicated a decreasing trend due to uptake of phenol and cyanide throughout cultivation. Toxicity to 100–1000 mg/L of phenol and 10–100 mg/L of cyanide was measured by measuring the relative transpiration over 13 days. At 100 mg/L of phenol and 10 mg/L of cyanide, only a small reduction in transpiration but no morphological changes were noticed. Both pollutants are absorbed through the root of the Eichhornia crassipes plant by plasmalemma and become accumulated into the root cells and stem of a plant. Thus, this study will be beneficial for the decontamination of highly polluted waste water.

由于城市化和工业化，水污染日益严重。废水污染因其对植物和人类的影响而引起关注。水葫芦（Eichhornia crassipes）因其植物修复效率而被用于去除污染物。在这项研究中，水葫芦（Eichhornia crassipes) 已经过测试，可以在批处理系统中同时消除单组分和二元组分水溶液中的苯酚和氰化物。植物在六种浓度的苯酚和氰化物以 (10:1) 的比例生长，即 100:10、200:20、300:30、500:50、700:70 和 1000:100 mg/L 的水溶液解决方案。评估了工艺参数的影响，例如苯酚和氰化物的初始浓度以及 pH 值。植物被发现能够在pH 8时的13天培养时间消除高达苯酚（300毫克/升）和氰化物（30毫克/升）的92.66％的96.42％计算出的ķ_米根长伸长为苯酚为 5.20 mm，V _max为 12.52 μg 苯酚/g root/h。然而，计算出的K _m氰化物的根长伸长率为 0.39 mm，V _max为 14.99 μg 氰化物/g root/h。在凤眼莲植物中，由于在整个栽培过程中对苯酚和氰化物的吸收，叶绿素、蛋白质和糖含量等生化参数已显示出下降趋势。通过测量 13 天的相对蒸腾作用来测量对 100–1000 mg/L 苯酚和 10–100 mg/L 氰化物的毒性。在 100 mg/L 的苯酚和 10 mg/L 的氰化物下，蒸腾作用仅略有减少，但没有观察到形态变化。两种污染物都通过凤眼莲的根部吸收植物通过质膜并积累到植物的根细胞和茎中。因此，这项研究将有利于高污染废水的净化。
