Abstract This article critically overviews the state-of-the-art of slurry sampling as an approach for minimization sample preparation prior to determination metals and metalloids in complex matrices by spectroanalytical techniques. Relevant factors involved optimization slurry-based analytical procedures dependence quality results on calibration method selected are discussed detail. The advantages limitations compared solid analysis highlighted discussed. Analytical applications reported...
The present work proposes the use of Agave sisalana (sisal fiber) as an natural adsorbent for ions Pb(II) and Cd(II) biosorption from waters. flame atomic absorption spectrometry was used quantitative determination study adsorption on solid phase. Fourier transform infrared spectroscopy (FT IR) to investigate sisal structure specific BET surface area analyzed. potential biosorbent removal aqueous solution considering followings parameters: pH, biomass amount contact time. Langmuir Freundlich...
Abstract The present article describes fundamentals and applications of multivariate techniques used for the optimization analytical procedures systems involving spectroanalytical methods such as flame atomic absorption spectrometry (FAAS), electrothermal (ETAAS), inductively coupled plasma optical emission (ICP OES), mass (ICP‐MS), considering main steps a chemical analysis. This way, experimental designs in sampling systems, digestion procedures, preconcentration instrumental parameters...
Agro-industrial waste, which is generated during the process of food production, has potential to contaminate significant quantities natural resources. Concurrently, cultivation edible mushrooms from waste materials that have been previously discarded undergoing exponential growth. This due nutritional value and their biotechnological in production enzymes industrial interest. The present study aims evaluate lignocellulolytic hydrolytic by mushroom Pleurotus pulmonarius on cocoa peach-palm...
This work investigated the xylanase production by fungi isolates from tropical agroforestry systems using peach-palm industrial waste as a substrate. Trichoderma stromaticum AM7 was best producer and there 160% increase in activity after optimizing Box–Behnken statistical design. The optimization process demonstrated that maximum occurred at 0.95% nitrogen concentration 6 days of cultivation 32°C, which achieved yield 1440 U g−1 dry initial Analysis scanning electron microscopy showed...
This study approaches the determination of nine elements from Brazilian carbonated soft drinks several flavors and manufactures using inductively coupled plasma optical emission spectrometry (ICP OES). The concentrations varied as follows: (in µg L-1: Cu: 4.00-78.0; Fe: 74.0-506; Mn: 20.0-66.0; Zn: 104-584) mg Ca: 4.81-16.2; K: 6.73-260; Na: 26.0-175; S: 1.43-5.41; P: 0.186-219). Principal component analysis has shown some tendencies to form two groups according drink flavor (orange cola),...
