Study of the effectiveness of a ZnO–TiO2 formulation in the degradation of humic substances in mature leachate by solar photocatalysis Brazil Nicoly Milhardo Lourenço Nohara, Helcio José Izário Filho, Adriano Francisco Siqueira, Leandro Gonçalves de Aguiar, Gabriel Caracciolo Koenigkam de Oliveira, et al. Revista Ambiente E Agua, 2023 Treatment of landfill leachate is an important environmental issue, especially in developing countries such as Brazil. Advanced oxidation processes (AOPs) have been considered interesting treatment alternatives. In this study, ZnO–TiO2 mixtures were incorporated into a paint polymer matrix and fixed onto supports. Paints were applied by overlapping coat layers on plates, resulting in high film thickness (600 ± 80 µm). Treatment of mature leachate by an AOP was conducted in a plug flow reactor connected to a stirred tank under solar irradiation. The objective was to evaluate the degradation of humic acid (HA) and fulvic acid + humins (FAH). The highest HA and FAH removal efficiencies were 62% ± 4.9% and 16% ± 4.2%, respectively. The kinetic model provided a coefficient of determination (R2) of 0.974. Rate constants for HA and FAH removal were 2.96 and 1.03 × 10−3 min−1, respectively. Statistical models for HA and FAH degradation had R2 values of 0.96 and 0.99, respectively. Both approaches indicated that HA degradation is greater at acidic pH and higher TiO2 concentrations. FAH degradation was favored by acidic pH and higher ZnO concentrations. Statistical models showed the same mean difference in conversion between replicate runs of HA and FAH, suggesting a uniform diffusion of fractions through catalysts.
 Keywords: heterogeneous photocatalysis, humic and fulvic acid, landfill leachate treatment, titanium dioxide, zinc oxide.

F-free mould powders for low carbon steel slab casting – technological parameters and industrial trials J. L. Klug, M. M. S. M. Pereira, E. L. Nohara, S. L. Freitas, G. T. Ferreira, et al. Ironmaking and Steelmaking, 2016 The choice of the mould powder for slab casting is a difficult task because mould powders have many important functions during the continuous casting of steel. CaF2 is a key ingredient in conventional mould slags since it reduces the viscosity, the liquidus temperature and the break temperature. Fluorine in mould powders is undesirable from the environmental and health points of view due to the following reasons: (i) evolves easily from slags, producing health-injurious gaseous substances, such as hydrofluoric acid; (ii) creates problems for storage and utilisation of solid waste and (iii) causes machinery corrosion. Aim of the present work is to describe the development of a new F-free mould powder for low carbon steel slab casting replacing CaF2 with B2O3. Laboratory tests and industrial trials were performed considering the technological parameters viscosity, break temperature and crystallisation tendency. From laboratory tests it was concluded that important technological parameters are similar when comparing the F-bearing mould powder (reference) and the new F-free B-bearing mould powder for low carbon steel slab casting: viscosity at 1300°C, break temperature, and crystallisation tendency. It was observed during industrial trials that a significant decrease of the submerged entry nozzle erosion was observed. The results were similar when comparing the F-bearing and the F-free performance: slag pool thickness measurements, melting behaviour, Al2O3 absorption, mould powder consumption and slabs superficial quality.
Comparative study of the quantity of volatile organic compounds in water-based paint and solvent-based applied polyurethane Ailton R. da Conceição, Ednilson A. R. Pimenta, Ronaldo S. Fujisawa, Evandro L. Nohara Macromolecular Symposia, 2012 Summary: The concern about the environmental impacts generated in the production of goods and services has increased last decades. The industry has used paints and varnishes in the manufacturing process have been pressed to improve air pollution prevention. Thus, the present work aims to identify the quantitative differences of VOC's and analyze the effect of VOC's in the burning rate, in a solvent and water-based paint, applied in the manufacture of automotive steering wheels. The results has showed that the solvent-based paint contains nine times more VOC's in your formulation in relation to water-based paint, when compared liquid and volatile organic compounds present in the solvent-based paint increase the speed of combustion of the polyurethanes samples. These data indicate that a discussion on the subject must be initiated in order to reduce these emissions that can harm society.
