Utilização do biocarvão de bagaço de laranja na remoção de tetraciclina em água residuária

Abstract: RESUMO Diversos estudos têm relatado a presença de micropoluentes emergentes em níveis de traços em diversas partes do mundo, sendo encontrados em esgotos sanitários, efluentes hospitalares, efluentes industriais, águas superficiais, ambientes marinhos e sedimentos. Neste contexto, o presente artigo se baseou no estudo da capacidade de remoção da tetraciclina nos efluentes utilizando um tratamento terciário à base de biocarvão de bagaço de laranja. A metodologia foi baseada no estudo das interações com o fárma… Show more

“…When analyzing the coefficients of determination (R 2 ), the treated sugarcane bagasse (SB NaOH ) showed better fit in Langmuir isotherm, where the herbicide molecules are adsorbed in monolayer. That result corroborate with the experiments of ABREU et al [58] with sugarcane biochar for the adsorption of Cadmium (Cd), and CARVALHO et al [59] who studied orange peel biochar for tetracycline removal. Analyzing the SB NaOH for the Langmuir model was noticed that the maximum adsorbed amount in the experiment (Table 2) was 13.720 mg.g -1 while the R L factor (separation factor at 100 mg.L -1 ) was 0.767 mgL -1 indicating that adsorption was favorable (0 <R L <1) that is the adsorbate prefer the solid phase than the liquid [47].…”

The fit in Langmuir model proposed that adsorption occurs by covering the monolayer of glyphosate molecules above surface of SB NaOH that is each site is responsible by adsorption of only one molecule cannot to occurs additional adsorption [60], further assuming that the adsorption takes with active sites of the adsorbent with equal affinity for the adsorbate in which interferences in the adsorption of neighboring sites are disregarded [59].…”

“…Também é possível verificar a presença de cinzas e que sua estrutura é composta por canais e partículas com cavidades profundas, arredondadas e abertas. SegundoCarvalho et al (2021), a estrutura se apresenta dessa forma devido a liberação da matéria volátil. Este efeito que pode estar relacionado à existência de algum material mineral que provoca um aumento da desintegração nas partículas do biocarvão.…”
