This study aimed to evaluate the effectiveness of bio-adsorbent from coconut husk for the removal of remazol red dye. The characteristics of coconut husk bio adsorbent are studied using Fourier transform infrared (FT-IR) and scanning electron microscope (SEM). The effects of different types of adsorbent and the effects of initial dye concentration on the removal of remazol red dyes were evaluated. The results showed that the percentage removal of remazol red dye by the treated bio adsorbent is higher compared to the untreated bio adsorbent, especially by activated coconut husk with 5 hours burning time in the furnace. The SEM results also show that the treated bio adsorbent morphology is more porous and rougher to improve the adsorption process. Meanwhile, FTIR analysis shows the reduction of peaks because of the removal of much lignin and hemicelluloses. The best adsorbent recorded is activated coconut husk at 5 hours burning time when it achieved 75% removal.

O descarte de efluentes têxteis não tratados nos meios aquosos pode ocasionar em um rápido esgotamento do oxigênio dissolvido, o que resulta em um desequilíbrio noecossistema. São vários os métodos utilizados na remoção de cor, e, dentre eles, a adsorção vem se mostrando como um método de tratamento simples, barato e eficiente. O objetivo deste trabalho consiste em avaliar a habilidade da biomassa mista de Aspergillus niger e capim elefante (Penissetum purpureum Schum) na remoção do corante Remazol Vermelho de uma solução aquosa sintética sob difrentes condições de temperatura (30, 40 e 50 °C), concentrações variando entre 25 e 105 mg/L, tempo de adsorção de 0 a 200 minutos e pH 2.0. O estudo cinético foi caracterizado pelo modelo de pseudo-segunda ordem. Já o modelo de Langmuir se mostrou o melhor ajuste linear das isotermas de adsorção, apresentando uma capacidade de adsorção de 3,42 mg g-1. A esponteneidade da reação de adsorção foi avaliada através daenergia lvire de Gibbs. O estudo termodinâmico indicou que a adsorção é favorável e espontânea, além de que o aumento da temperatura ocasiona em uma redução na capacidade de adsorção. Estes resultados obtidos em efluentes sintéticosdemonstram que o adsorvente misto produzido neste estudo é uma alternativa promissora no tratamento de efluentes contaminados com Remazol Vermelho.
