RESUMO A contaminação do solo tem sido motivo de muita preocupação em diversas regiões do mundo. A geração desenfreada de resíduos sólidos e sua disposição inadequada têm agravado o risco de contaminação dos solos. O presente artigo teve por objetivos o tratamento e a refuncionalização do solo contaminado por lixiviado do aterro sanitário urbano do município de Altinho (PE). A descontaminação foi realizada por meio dos processos Fenton e foto-Fenton com luz negra e luz solar, sendo avaliado o percentual de conversão de carbono orgânico total. Após o tratamento com o foto-Fenton solar, o solo apresentou-se bastante ácido, com pequenas concentrações de íons inorgânicos, elevada saturação por alumínio e baixo grau de saturação por bases, revelando-se um solo infértil. Para a refuncionalização do solo foi adicionado lodo de esgoto nas proporções de 10, 30 e 50% em relação à massa do solo pós-tratado e validado pelo plantio da espécie Coriandrum sativum L. Os melhores resultados para o crescimento da raiz, comprimento total da planta, quantidade de folhas e massa das plantas foram obtidos para o tratamento com inserção de 30% de lodo de esgoto. Esse tratamento apresentou percentual de inibição de raízes de 13,2%, não representando risco de toxicidade para a espécie Lactuca sativa L. Também foi observado o aumento da capacidade de troca de cátions, do índice de saturação por bases e dos níveis de nitrogênio e fósforo, além da redução da saturação por alumínio, revelando melhoria nas condições agronômicas do solo.

Dyes are commonly used in various industries and unfortunately many of them are discharged into water bodies, causing environmental problems. In the current study, three hydrophobic, halogen‐free ionic liquids were synthesised and their capability as extracting agents was evaluated using four reactive dyes (CI Reactive Blue 4, CI Reactive Black 5, CI Reactive Orange 16 and CI Reactive Red 2). The ionic liquids, immiscible with the aqueous phase, could extract the reactive dyes from aqueous solutions, withdrawing the same amount of weight. The effects of pH and temperature on the extraction process were also studied. Trioctylmethyl ammonium ethylenediaminetetraacetate displayed a high extraction efficiency (99%), where only 33 mg of ionic liquids extracted 50 mg of CI Reactive Blue 4. Fourier Transform–infrared spectroscopy was used to screen the interaction between the ionic liquid and CI Reactive Blue 4 during the extraction stage.

An example of biosorption is when the sorbent is made from a biodegradable material. Biosorption is now being seen as a simple, cost-effective, and environmentally acceptable alternative to traditional pollution treatment methods. Bioremediation is one of the branches of bioremediation that is used to minimise pollution in the context of incorrect dye waste disposal. The sorption isotherm of Ethyl Violet onto graphene oxide were analyzed using three models—pseudo-1st, pseudo-2nd and Elovich, and fitted using non-linear regression. Statistical analysis based on root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), corrected AICc (Akaike Information Criterion), Bayesian Information Criterion (BIC) and Hannan–Quinn information criterion (HQC) that showed that the pseudo-second-order model was the best which was the same finding from the original published work. The calculated evidence ratio was 11 with an AICc probability value of 0.91 indicating that the best model was at least 11 times better than the nearest best model, which was pseudo-1st. Further analysis is needed to provide proof for the mechanism usually tied to this kinetic. Nonlinear regression analysis using the pseudo-2nd order model for the highest concentration tested, which was 10 mM, gave values of equilibrium sorption capacity qe of 30.928 mg/g (95% confidence interval from 29.328 to 32.527) and a value of the pseudo-2nd-order rate constant, k2 of 0.020 (95% confidence interval from 0.011 to 0.028).
