Estudo químico das flores de Hortia oreadica (Rutaceae)
(Universidade Federal de São Carlos, 2018-07-27)
The present work describes the analysis of apolar and polar extracts from flowers of Hortia oreadica, a species of the family Rutaceae. Since these flowers had not been widely studied, and due to the chemosystematic value ...
Desenvolvimento de método analítico com emprego da espectrometria de absorção atômica para a determinação de Cd, Fe, Pb e Zn em amostras de interesse alimentício
(Universidade Federal de São Carlos, 2008-07-31)
Analytical chemistry plays a fundamental role in proposing fast and reliable procedures to analyze food samples. Proper selection and introduction of complementary foods reduces the vulnerability to micronutrient deficiencies. ...
Determinação sequencial rápida de As e Sb, Bi e Pb por espectrometria de absorção atômica com geração de hidretos
(Universidade Federal de São Carlos, 2012-03-22)
In this study it was developed two systems, one for the fast sequencial determination of As and Sb and other for Bi and Pb using flame atomic absorption spectrometry with hydride generation. To optimize the system for the ...
Obtenção de blenda biodegradável PLA: amido para a incorporação do micronutriente manganês
(Universidade Federal de São Carlos, 2016-09-30)
The incorporation of particulate fertilizers in polymeric fibers aims to release these active principles from a substrate with a high surface area and biodegradable and biocompatible properties. It also seeks to provide ...
