玻璃制造工业产生难以管理的有害流出物,并且在露天处置时引起许多环境问题。在这项研究中,尝试研究水莴苣(PistiastraterotesL.)的植物修复可行性,一种自由漂浮的水生植物,以不同浓度(0、25、50、75和100%)从玻璃工业废水(GIE)中去除六种重金属。经过40天的实验,结果表明,25%的GIE稀释液对重金属的去除效果最大,即Cu(91.74%),Cr(95.29%),铁(86.47%),Mn(92.95%),Pb(87.10%),和锌(91.34%),分别。生物蓄积性,易位,和Pearson相关性研究表明,P.层植物性部分吸收的重金属量与浓度显着相关。最高的生物质产量,叶绿素含量,相对增长率,在25%的GIE处理中也注意到生物量生产率。此外,为预测P.stratiotes的重金属吸收而开发的多元线性回归模型在确定GIE特性的影响方面也显示出良好的性能。模型显示出较高的决定系数(R2>0.99),低平均归一化误差(MANE=0.01),和高模型效率(ME>0.99),支持已开发方程的鲁棒性。这项研究概述了使用P.stratiotes对GIE进行生物处理的有效方法,以减少与不安全处置相关的风险。
The glass manufacturing industry produces hazardous effluent that is difficult to manage and causes numerous environmental problems when disposed of in the open. In this
study, an attempt was made to
study the phytoremediation feasibility of water lettuce (Pistia stratiotes L.), a free-floating aquatic macrophyte, for the removal of six heavy metals from glass industry effluent (GIE) at varying concentrations (0, 25, 50, 75, and 100%). After a 40-day experiment, the results showed that 25% GIE dilution showed maximum removal of heavy metals i.e., Cu (91.74%), Cr (95.29%), Fe (86.47%), Mn (92.95%), Pb (87.10%), and Zn (91.34%), respectively. The bioaccumulation, translocation, and Pearson correlation studies showed that the amount of heavy metals absorbed by vegetative parts of P. stratiotes was significantly correlated with concentrations. The highest biomass production, chlorophyll content, relative growth rate, and biomass productivity were also noted in the 25% GIE treatment. Moreover, the multiple linear regression models developed for the prediction of heavy metal uptake by P. stratiotes also showed good performance in determining the impact of GIE properties. The models showed a high coefficient of determination (R2 > 0.99), low mean average normalizing error (MANE = 0.01), and high model efficiency (ME > 0.99) supporting the robustness of the developed equations. This
study outlined an efficient method for the biological treatment of GIE using P. stratiotes to reduce risks associated with its unsafe disposal.
