Equilibrium Uptake and Bioaccumulation of Basic Violet 14 Using Submerged Macrophyte Hydrilla verticillataThe percentage removal and uptake capacity of Basic Violet 14 using Hydrilla verticillata with living biomass was studied under batch conditions. The survival of H. verticillata was studied using the chlorophyll content in the living biomass. Bioaccumulation of Basic Violet 14 using H. verticillata was tested by varying the wet sorbent dosage (0.5-2.5 g), initial pH (3-8), and initial dye concentrations (5-25 mg L À1 ). The results show that the plant was effectively accumulating the Basic Violet 14 dye. The uptake capacity of Basic Violet 14 dye was observed as 5.9 and 21.3 mg g À1 at the initial dye concentration of 5 and 25 mg L À1 , respectively, for a biomass of 5 g L À1 (wet weight) at pH 7.0 for 144 h. In general, the plant growth was found to be normal at lower concentrations and showed higher removal efficiency. It was also observed that removal efficiency of H. verticillata was found to decrease with increase in initial dye concentration. The biomass sample surface was analyzed using SEM imaging and functional groups present in the biomass were analyzed using FTIR. The equilibrium uptake capacity was analyzed by Langmuir and Freundlich isotherms. The equilibrium data was found to be fit well to both Langmuir and Freundlich isotherm models with higher coefficient of determination. In the last decades, the use of phyto-technologies has become an effective alternative method for the remediation of contaminated water systems [5]. Phytoremediation is defined as the use of plants, both terrestrial and aquatic; to absorb, concentrate, and precipitate contaminants from polluted aqueous sources with low contaminant concentration in their roots [6]. The U.S. Environmental Protection Agency (EPA) seeks to protect human health, environment associated with hazardous waste sites, and encourages the development of innovative technologies such as phytoremediation to clean up hazardous sites [7].Most of the work has been already established on the accumulation of heavy metal using plant such as Hydrilla verticillata for cadmium accumulation [8], Pistia stratiotes for arsenate uptake [9], Wolffia globosa for an indicator of metal pollution in the water bodies [10], P. stratiotes for lead uptake [11]. Only limited work has been established for the removal of textile dyes using living aquatic plant. In this present study, H. verticillata was used as living biomass for the accumulation of basic dye from synthetic dye solution.Basic dyes are salts of the colored organic bases containing amino and imino groups and also combined with a colorless acid, such as hydrochloric or sulfuric acid. They are brilliant and most fluorescent among all synthetic dyes. Basic Violet 14 was selected as a model compound to estimate the accumulation capacity of H. verticillata. It is a submerged plant, and it has been observed to grow luxuriantly in various contaminated water bodies of India [12]. H. verticillata has attracted the attention ...

-Industries engaged in dyeing operation generate coloured effluent due to the presence of spent dyes. Adsorption is among the various treatment processes employed for removal of dyes from effluents. Activated carbon is mostly used as an adsorbent in the treatment process. Attempts have been made by researchers to use non-conventional, low-cost, naturally-occurring biomass as adsorbents, including fruit peals, seeds, leaves, bark, sawdust, straw, ash, sludge and others that are abundantly available. The literature indicates that the dye adsorption capacities of these non-conventional biomasses largely depend on the methods of processing and the types of dyes. This review highlights methods used to prepare the adsorbents, along with their adsorption capacity for removal of different dyes from effluents.
