“…Low et al (1995), reported the biosorption of basic dyes (methylene blue and Victoria blue) by water hyacinth roots with maximum sorption capacities of 128.9 and 145.9 mg/g respectively. Kanawade and Gaikwad (2011) also reported that the adsorption data of methylene blue by water hyacinth roots correlated well with the Langmuir and Freundlich isotherms. Sivaraj et al (2010), reported the removal of reactive Magenta B and reactive Turquoise Blue dyes using activated carbon obtained from water hyacinth.…”

“…High efficiency, availability and low cost have been major reasons for the use of plants, agricultural and biological materials as adsorbents for aqueous pollutants. Dye effluents in aqueous streams represent another group of water pollutants that require great attention by virtue of the large amount of production and use of dyes globally (Imamura et al, 2002;Kanawade & Gaikwad, 2011). The reduction of light penetration in water bodies, especially to benthic organisms and the low biodegradability of dyes present them as potential toxicants to marine lives.…”

The use of dried water hyacinth stem and leaves was also studied by El-Wakil et al (2013) …”

Water hyacinth (Eichhornia crassipies) has proved to be a menace in water bodies and studies are on, in the direction of solving this problem; one of which is to discover economic uses of water hyacinth. Adsorption of heavy metals and dyes from aqueous solutions by activated carbon derived from water hyacinth is one of such studies. In this study, dried and pulverized water hyacinth shoot was used for the sorption studies. This is in the bid of eliminating the rigours of producing activated carbon, thereby saving time and cost. The adsorption capacity of water hyacinth shoot for Methylene Blue dye was studied as a function of initial metal ion concentration in a batch system. Results showed that adsorption increased with methylene blue dye concentration. Seven adsorption isotherms, namely Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Florry-Huggins, Harkins-Jura and Henry's isotherms were applied to the adsorption data. Isotherm parameters showed that all the isotherms correlated well with the adsorption data. The maximum adsorption capacity of Methylene Blue dye to the dried water hyacinth shoot was found to be 58.14mg/g. The use of dried water hyacinth shoot would appreciably save the time and cost for producing activated carbon but not without some compromise of efficiency.

Abstract-Phytoremediation is defined as the use of plants and their associated microorganisms to remove harmless pollutants from contaminated sites. It is a promising approach in the treatment of dye wastewater due its cost-effectiveness. The aim of this study was to determine the effectiveness of water hyacinth (Eichhornia crassipes) in removing color. Water hyacinth was used to treat 50 mg/L of methylene blue (MB) and 50 mg/L of methyl orange (MO) for 20 days under ambient temperature (30±1 °C). The pH of the synthetic dye wastewater was observed throughout 20 days. Results obtained showed that percentage of color removal was higher for MB compared to MO which were 98.42% and 66.80% respectively. The relative growth of Eichhornia crassipes in MB and MO were also being determined. The cell structure of Eichhornia crassipes (leaf, shoot and root) before and after the plants were exposed to dye wastewater was analysed using light microscope.

Sorption Equilibrium of Azo Dyes Direct Orange 26 and Reactive Blue 81 onto a Cheap Plant Sorbent/Równowaga Sorpcji Barwników Azowych Direct Orange 26 I Reactive Blue 81 Na Tanim Sorbencie Roślinnym

Azo dye-plant sorbent system was investigated in the paper. Direct Orange 26 and Reactive Blue 81 azo dyes were sourced from Boruta-Zachem Kolor Sp. z o.o. Mechanically and chemically modified rye straw was used as a "low-cost" biosorbent. During experiments, dye concentration changes in the solution and sorbent in time were measured at constant temperature until equilibrium was reached. Sorption equilibrium was described by 2-parameter (Freundlich, Langmuir) and 3-parameter (Redlich-Peterson and Radke-Prausnitz) equations widely used in adsorption studies. Characteristic coefficients of equations were determined and the proposed approximations of the results of experimental studies were evaluated statistically. Higher sorption capacity was obtained for Direct Orange 26 than for Reactive Blue 81.
