Textile companies release wastewater containing lots of colors including Methylene Blue (MB) dye. Those colors are harrmful for human well being. Various procedures have been utilized to expel the color from industrial wastewater. Out of different methods used in practice, adsorption was observed to be exceptionally successful and effective. The reason behind the especiality is when nanocomposites are utilized as an adsorbent, as it has a better adsorption limit, selectivity, and solidness than nanoparticles. In this research, a peculiar synthesis of adsorbent Graphene Oxide Silica [GO-Si] is carried out and it is used to remove methylene blue dye from texile industry wastewater. Analysing the performance of MB dye removal from the waste water using this adsorbent seems to be more effective. Various studies have been carried out for successful analysis of the performance such as adsorption isotherm study, Freundlich and Langmuir analysis. In addition the adsorption process was well explained by a pseudo-second-order kinetics models.

The ability of bagasse adsorbents to adsorb methylene blue without activation using 0.5 M H2SO4 solution was examined. Methylene blue is widely used in the textile industry because it produces bright colors, and the dyeing process is fast and easy. This research aims to determine the optimum adsorption conditions, namely the variations in contact time, dye concentration, adsorbent mass, and pH effect on methylene blue, which were carried out using the batch method. Furthermore, the adsorbents were characterized by FT-IR and SEM. The optimum state of the bagasse adsorbent to adsorb methylene blue dye has a mass of 0.5 grams, a contact time of 30 minutes, a concentration of 50 ppm, and a pH of 5. The character of the adsorbent after activation with H2SO4 was better than without activation. The highest adsorption efficiency of methylene blue dye in the batch method was 99.67%. The FTIR spectrum of the bagasse adsorbent showed OH, C-H, C=O, C=C, and C-O functional groups. The adsorption isotherm model for methylene blue dye follows the Langmuir isotherm since the graph obtained is linear with the correlation coefficient (R2) = 1, where the adsorbent has a homogeneous surface.

Socioeconomic Benefits

The textile industry, very important for the world economy, generates an effluent containing dyes, and which, when discarded in water bodies without proper treatment, can cause impacts to human health and the environment. One of these widely used dyes is methylene blue, whose characteristics are high solubility in water and its toxic potential, and which effects range from eye irritations, nausea, vomiting and even mental confusion. Among the potential adsorbents of this dye is chitin, which is a biopolymer extracted from the shrimp exoskeleton. Aiming at the development of a low-cost adsorbent material with potential use in the textile effluent treatment industry, the ability to remove methylene blue dye by shrimp residue chitin, obtained by eleven different methodologies, was verified. The three most efficient treatments reached approximately 75% of dye removal, proving the high adsorption power of shrimp residue. In addition to providing technological development of materials, the research brings socioeconomic benefits to the fishermen’s colony with the use of shrimp residue for the adsorption of other waste from the textile industry, contributing to the sustainability of both activities and reducing the environmental impact.
