This study was carried out to investigate the potential of duckweed (Lemna minor L.) for bioremediation of C.I. Basic Red 46 (BR46) solution. Our results revealed the notable ability of the plant species in biological degradation of BR46. The reusability of the plant in long‐term repetitive operations was also confirmed. The decolorization efficiency was extremely dependent on different operational parameters such as initial dye concentration, pH, temperature, and amount of plant. Interestingly, activities of superoxide dismutase and peroxidase as antioxidant enzymes were increased in different concentrations of the dye. In contrast, catalase activity declined in duckweed plants exposed to the dye. An artificial neural network (ANN) model was developed to predict the biological decolorization efficiency. The obtained data indicated that ANN provide realistic predictive performance (R2 = 0.981). © 2012 American Institute of Chemical Engineers Environ Prog, 32: 1082–1089, 2013

“…These results confirm the ability of S. grossus plants to decolourise MB dye. In previous studies, 98% MB was removed using Limna minor after six days [13], while a removal effiency of 65.7-89.30% was obtained by [14] through an adsorption process using peat with MB concentration of 19-134 mg/, which is comparable with our results.…”

Phytoremediation is an emerging technology that should be considered for the remediation of contaminated sites because of its aesthetic advantages and long-term applicability. The possibility of Scirpus grossus for degradation of a basic dye, methylene blue (MB) was investigated. The effect of the operational parameter of different dye concentrations (0, 200, 400, 600, 800 and 1000 mg/L) was determined, and the water quality parameters namely pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total organic carbon (TOC) were monitored. The UV-Visible absorption confirmed the degradation of MB within 72 days. The removal efficiency of methylene blue dye from synthetic wastewater was determined to be in the range of 86 -38% for all treatments at different concentrations (200 -1000 mg/L) respectively. Furthermore, the highest removals for BOD, COD in 400 mg/L and TOC in 200 mg/L MB were 69, 58 and 63% respectively.

Kemungkinan Scirpus grossus untuk degradasi pewarna asas, metilena biru (MB) telah dikaji. Kesan parameter operasiiaitu kepekatan pewarna yang berbeza (0, 200, 400, 600, 800 dan 1000 mg/L) ditentukan dan parameter kualiti air iaitu pH, oksigen terlarut (DO), permintaan oksigen biokimia (BOD), permintaan oksigen kimia (COD) dan jumlah karbon organic (TOC) dipantau. Penyerapan UV cahaya nampak mengesahkan degradasi MB dalam masa 72 hari. Kecekapan penyingkiran pewarna metilena biru daripada air sisa sintetik telah ditentukan dalam lingkungan 38 -86% untuk semua rawatan dalam kepekatan yang berbeza (200 -1000 mg/L) masing-masing. Tambahan pula, penyingkiran tertinggi bagi BOD, COD dalam 400 mg/L dan TOC dalam 200 mg/L MB masing-masing adalah 69, 58 dan 63%.

“…The experiment was conducted for seven days of contact time, which matched values commonly reported in the literature regarding L. minor [12,13] for the treatment of textile dyes. In addition, Reema et al [9] mentioned that the ability of L. minor for uptake of dye molecules escalates with an increase in contact time for initial dye concentrations. The mean values of the treated or final (outflow) dye concentrations for all dyes were higher in the control ponds than in the planted ponds (Table 4).…”

“…Various methods have been used for textile dye removal including chemical and physical processes such as oxidation, coagulation and flocculation, adsorption by activated carbon and membrane filtration [2,3,8,9]. Biological treatment alternatives such as constructed wetland ponds are likely to be sustainable and cost-effective [10,11].…”

The study assesses the performance of experimental wetland pond systems vegetated by Lemna minor L. (common duckweed or lesser duckweed) for textile azo dye removal. The objectives are to assess the influence of L. minor on water quality parameters, compare the dye and chemical oxygen demand (COD) removal of four dyes (Acid Blue 113, Reactive Blue 198, Direct Orange 46 and Basic Red 46) with each other, and monitor the effect of dye accumulation as a function of the relative growth rate (RGR) of L. minor. Findings indicate that the simulated shallow pond systems remove BR46 (low concentration) significantly (p < 0.05) higher than other dyes, and the ponds containing L. minor outperformed control ponds by around 51% in mean removal efficiency with a potential of L. minor for phytoremediation of approximately 13% efficiency.
