Adsorption Decolorization Technique of Textile/Leather – Dye Containing Effluents

Abstract

The purpose of this study was to evaluate the potential of ion exchange resins to remove the color from industrial wastewaters. In textile-leather dyeing, paper, colour, printing, cosmetics, pharmaceutical and other industries the synthetic dyes are extensively used. Adsorption techniques are much used to remove certain classes of pollutants from waters, especially from industrial colored wastewaters. In recent years, functional polymers have been increasingly tested as a potentially alternative to traditional adsorbents due to their vast surface area, perfect mechanical rigidity, adjustable surface chemistry and feasible regeneration under mild conditions. The strongly basic anion exchanger resins were used as an adsorbent for the acid, direct and reactive dyes adsorption from the coloured wastewaters.

Reusability of brilliant green dye contaminated wastewater using corncob biochar and Brevibacillus parabrevis : hybrid treatment and kinetic studies

“…Cost is an important parameter to select a proper adsorbent. Among the several techniques, adsorption using agricultural biomass has received considerable attention because of the following reasons: (i) agro-based wastes are available in large quantities at a cheaper price, (ii) demonstrate high dye removal rates, (iii) ability to treat concentrated dye containing effluent, and (iv) its reuse and recyclability [29][30][31]. In literature, different agro-wastes have been used for dye removal from effluents such as jute sticks [32], Jamun leaves [33], rice straw [34], wheat straw [35], banana peel [36], pine wood [37], etc.…”

Методы Удаления Пигментов Из Сточных Вод

“…OH , ( (1,78). Восстанавливаясь, озон разлагает хлорированные углеводороды, фенолы, пестициды и ароматические углеводороды [33].…”

“…Очистка воды в настоящее время представляет собой одно из важнейших направлений прикладной науки. Сбросы сточных вод сложного состава, содержащих пигменты, вызывают серьѐзную обеспокоенность у природоохранных регулирующих органов [1]. Неиспользованные в производстве вещества сбрасываются со сточными водами, которые характеризуются высокими показателями цветности, биохимического потребления кислорода (БПК), химического потребления кислорода (ХПК), рН, температуры, мутности и содержания токсичных химических веществ.…”

Mapping Water Quality Parameters in Urban Rivers from Hyperspectral Images Using a New Self-Adapting Selection of Multiple Artificial Neural Networks

“…The fishery industry along the river banks has some remains of fodder leaking into the river. Some light industries, such as textiles, contribute contaminants into the river [40,41]. The Shiqi River is adjacent to an estuary, and countercurrent frequently occurs, causing waste aggregation in the river [42].…”
