There is growing interest in the recovery of pure palladium (Pd) compound from cemented Pd spent electroplating solutions due to increasing demand for Pd, and there considerable motivation develop an efficient process. In conventional methods leaching metal, HCl containing oxidizing agents are employed. this work, ethylene glycol (EG) replaced water as a diluent solution such H2O2, NaClO NaClO3...

Abstract The characteristics of cellulose nanofibers (CNFs) depend on many factors such as the raw material, type and intensity pre-treatment, severity mechanical defibrillation process. relationship among is complex but crucial in determining final, fit-for-use CNF properties. This study aims to find between properties morphology, aspect ratio, nanofibrillation yield, transmittance cationic de...

O objetivo deste trabalho foi avaliar a desinfestação, propagação in vitro e subcultivo de ora-pro-nóbis. No primeiro experimento, realizou-se desinfestação dos explantes com diferentes concentrações hipoclorito sódio (2%, 4%, 6%). segundo, realizada 600 segmentos nodais, sob meio MS (MS, MS/2, MS/4) combinações fitorreguladores: 1) ANA (0,5μM) + BAP (0,5μM); 2) (1,0μM); 3) (1,5μM); 4) (2,0μM);...

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...

• UV/chlorination of diclofenac sodium (DS) followed pseudo-first-order kinetics. DS degradation was affected by chlorine dosage, solution pH, humic acid and bicarbonate concentrations. The relative contributions OH RCS to elimination are dependent on free dosage. Four transformation pathways involved C-N cleavage, condensation, hydroxylation, decarboxylation were proposed. UV/chlorine presente...

Abstract The outbreak of the COVID-19 pandemic has adversely affected most important areas modern world. One challenges related to counteracting effects it was necessary develop methods for quantitative determination pharmaceuticals used in treatment patients suffering from this disease and its long-term effects. Budesonide (BUD) is a widely available inexpensive corticosteroid extensively not ...

The eggshell is a biomineral consisting of CaCO3 in the form calcite phase and pervading organic matrix (1–3.5 wt.%). Transforming particles into calcium phosphate (apatite) micro-nanoparticles opens door to repurposing waste as materials with potential biomedical applications, fulfilling principles circular economy. Previous methods obtain these consisted mainly two steps, first one involving ...

Quince (Cydonia oblonga) is a pome fruit belonging to the Rosaceae family and produced in temperate climates. The popularity of quince increasing year by year. It likely become highly popular near future. its leaves are rich bioactive compounds. In addition providing significant health benefits, different parts plant an important source raw materials, with applications pharmaceutical sectors. M...

Washing procedures applied to fresh produce have the potential to reduce contamination from the surface of the product. However, the wash water may also serve as a source of contamination or has great potential to result in cross-contamination. The objective of this study was to evaluate process handling cross-contamination potential and pathogen removal of initially low numbers of attached cel...
