The copper tetraphenylporphyrin (CuTPP) was prepared within a NaY zeolite cavity to investigate the electrocatalytic behavior of CuTPP upon oxidation hydrazine and cysteine. amount 0.067 mmol g−1 obtained in cavities. Cyclic voltammetry showed only an anodic peak at 320 mV that assigned CuI CuII. This not affected by supporting electrolyte nature or solution pH. electrode activity oxidize both cysteine hydrazine, however for weak, possibly as result adsorption product (cystine). Although...
Abstract Kraft mill effluents were biologically treated in an aerated lagoon (AL) (3.4 L) to evaluate the behavior of aromatic compounds by UV‐vis spectroscopy. Under aerobic conditions, biological oxygen demand (BOD 5 ) removal was between 84% and 95%, whereas soluble chemical (COD s ranged 40% 60%. A slight increase observed VIS 436 /COD relationship (0.101–0.110), indicating that color reduction less than total organic matter expressed COD . Additionally, low values UV 254 /UV 280...
In the present study performance of an activated sludge system (AS) and aerated lagoon (AL) are compared for treatment kraft cellulose effluents. Both reactors were operated at organic loading rates (OLR) up to 9 g COD/L. d. The presented better high OLR than with removal percentages 57-67% 95% COD BOD(5), respectively. specific compounds always slightly higher in case AS AL exception total phenolic which concentration increased former. Furthermore analyzed fractions from effluents indicated...
The pulp industry generates high effluent flows, which contain chemical oxygen demand (COD), biochemical (BOD5), colour and ecotoxicity. This study aimed to evaluate the treatment of Kraft by aerated lagoon modified with sponge support media (APG). It was assessed arrangement in lagoons organic load rate (OLR) 0.2 kgCOD m-3 d-1, after that, OLR variation from 1.2 d-1. parameters evaluated were BOD5, COD, colour, lignin derivatives, total phenolic compounds acute ecotoxicity D. magna. COD...
Brazil is considered a world leader in paper production. It estimated that the sector contributes 46.5% of national gross domestic product, and its effluents have high concentrations organic matter recalcitrant compounds which can cause coloration ecotoxicity, generating impact if not properly treated. A potential strategy for treatment this wastewater bioaugmentation with native bacteria isolated from industrial sludge effluent, which, due to their metabolism adapted adverse environmental...
This study aims to evaluate the viability of treatment wastewater from textile industry by Moving Bed Biofilm Reactor (MBBR).The was characterized chemical oxygen demand (COD), biological (BOD 5 ), spectral area, toxicity, total suspended solids (TSS) and volatile (VSS) before after treatment.The occurred in different organic loading rates 0.3 up 9.0 g COD/L.d with 4 stages: adaptation at gCOD/L.dand 3 stages 1.2, 3.0 gCOD/L.d.This reactor operated for 107 days, reaching 65% removal COD, 94%...
POTENTIAL USE OF SERPENTINITE FOR CO 2 MINERAL STORAGE.Rising anthropogenic emissions are considered a major contributor to the greenhouse effect.There several options for reducing atmospheric CO2 levels, and among these alternatives, Carbon Capture Storage (CCS) has been identified as an effective promising approach.This work investigated feasibility of using serpentinite vehicle carbon storage presenting source-sink match.The main results confirmed that is appropriate carbonation process...
No presente estudo é analisado como a Educação Ambiental se apresenta na ultima versão homologada da Base Nacional Curricular Comum e partir sua manifestação expor elementos de contradições retrocessos no campo temática transversal uma vez que, possui construção histórica que fundamenta efetividade currículo escolar. Nesse sentido, tivemos objetivo analisar sob perspectiva do método complexidade qual o espaço dedicado escolar apontar para enfrentar as contrarreformas educação brasileira. Foi...
The pulp industry uses more than 40 m3 of water per ton produced, generating high effluent flows. In general, it presents concentrations organic matter, color and ecotoxicity. most widely used treatment systems in the are biological, including moving bed biofilm that efficient removing biodegradable matter. This work evaluated removal total phenolic compounds, lignin derivatives Kraft cellulose using reactor (MBBR), also support media development by solid analysis scanning electron...
This study investigates the evolution of biofilm matrix responsible for treating effluent from a pulp mill and identifies microbial community by 16S rRNA gene sequencing. In addition, biocarrier promising functional structure with better specific features formation than traditional polyurethane carriers was explored. The average removal efficiencies were 43.7% chemical oxygen demand (COD) 62.7% biochemical (BOD5). color increased during treatment, indicating anoxic zones being formed in...
Krishi Vigyan Kendras (KVKs) were established to provide essential agricultural education and support farmers at the grassroots level. These centers play a crucial role in disseminating advanced technologies practices improve productivity sustainability of farming. Front Line Demonstrations (FLDs) extension programs KVKs, providing platform demonstrate validate new technologies, practices, innovations directly farmers' fields. They are an integral part services, facilitating smooth effective...
Kraft mill effluents treated by activated sludge show a reduction in acute toxicity. However, their discharges produce hormonal effects an aquatic ecosystem, due to the sterols metabolites as androstenedione contained effluents. Daphnids bioassays are powerful approach for determining there relative sensitivities depending on species. The main objective of this study is determine sensitivity D. magna and obtusa when exposed kraft effluents, diethylstilboestrol (DES), (AED). were tested using...
