Abstract Experimental viscosity and density data of four natural gases are presented for temperatures from 100 to 340 F pressures 8,000 psia. A correlation is discussed results reported. Introduction This investigation one several efforts by the authors provide pure hydrocarbons mixtures. Results some their mixtures have been presented. Several predictive methods correlations also paper presents experimental confirms a in previous study. APPARATUS The viscometer was described previously....
Microwave-assisted sample preparation using diluted nitric acid solutions is an alternative procedure for digesting organic samples. The efficiency of this depends on the chemical properties samples and in work it was evaluated by determination crude protein amount, fat original carbon. Soybeans grains, bovine blood, muscle viscera were digested a cavity-microwave oven oxidant mixtures different concentrations. digestion based residual carbon content element recoveries inductively coupled...
The principles of green analytical chemistry have led to the development procedures that are increasingly sustainable. Different metrics been created for evaluation greenness, although determination nature new methods remains challenging, including extraction involve use natural deep eutectic solvents (NADES). In this study, following five chemical greenness were considered: National Environmental Methods Index (NEMI), Green Analytical Procedure (GAPI), Eco-Scale, GREEnness (AGREE), and...
Since early times, propolis has been used in folk medicine. The red propolis, collected the northeast region of Brazil highlighted due to its popular use as an antimicrobial, with anti-inflammatory and healing properties, which are associated chemical composition. Here, we combine a bacterial membrane treat wounds diabetic mice. This work aims evaluate biocurative from cellulose mice wound model. Biocuratives different extracts were produced. qualification quantification presence compounds...
Deep eutectic solvents (DESs), a novel class of eco-friendly solvents, are attracting considerable attention in extraction techniques. In this study, hydrophobic DES, created by combining quaternary ammonium salt and hexanoic acid, was coated onto commercial cellulose membrane for polycyclic musks (cashmeran, celestolide, galaxolide, tonalid) microextraction from surface waters followed gas-chromatography–mass spectrometry (GC MS) analysis. A series DESs were synthesized characterized to...

The distribution of arsenic in the different tissues tilapia fish is determined by exposure time and depuration rate. mechanisms toxicity/carcinogenicity depend on species involved biotransformation processes. After a 7-day period, accumulation inorganic (iAs) studied was order: liver > stomach gills muscles. In bioaccumulation assays, values organ uptake constant (ka) ranged from 0.06 to 0.51 mL g−1 d−1, while rate (kd) were range 0.03–1.15 d−1. Higher iAs factor (BCF) observed for (3.1...

A single microwave-assisted acid-decomposition procedure is proposed for sample preparation of plant- and bovine-derived materials prior to multielement determination by inductively coupled plasma−optical emission spectrometry (ICP−OES). The involved grinding in a cryogenic mill reduce particle sizes increase the surface area acid attack, followed decomposition under high pressure temperature. heating program was employed efficiently destroyed most organic matrix using small volumes nitric...
