1. HIDROGÉIS NANOCOMPÓSITOS DE POLISSACARÍDEO COM ZEÓLITA: AVALIAÇÃO DO PROCESSO DE ADSORÇÃO DO PESTICIDA PARAQUAT
In this work, nanocomposites formed from the natural polymer carboxymethylcellulose in combination with the polyacrylamide polymer and zeolite were obtained and characterized in relation to pesticide sorption capability. Hydrogels are three-dimensional network with large capacity of water or biological fluid adsorption. They have biocompatibility, biodegrada

2. DLLME-GC/ECD Method for the Residual Analysis of Parathion-Methyl and its Application in the Study of the UV-Photodegradation Process
A new method has been developed to determine trace levels of organophosphorus pesticide parathion-methyl in water samples by using dispersive liquid-liquid microextraction (DLLME), followed by gas chromatograph coupled with electron capture detector (GC/ECD) analysis. The optimized and validated method showed high extraction recovery (101.1%), high enrichmen

3. TRANSPORTE DE AGROTÓXICOS E USO DE ÁGUA EM DIFERENTES MANEJOS DE IRRIGAÇÃO DE ARROZ / PESTICIDE TRANSPORT AND WATER USE IN DIFFERENT IRRIGATION MANAGEMENTS ON RICE PADDY
O sistema produtivo de arroz irrigado é caracterizado pela ampla utilização de agroquímicos e grandes volumes de água para a irrigação por inundação. Devido à permanência de lâmina de água sobre o solo, podem ocorrer perdas de água por escoamento superficial e percolação. Juntamente com essa água, os agrotóxicos podem ser transportados, pre

4. Electrochemical control of aqueous solution pesticide: study for the degradation of 2,4-dichlorophenoxyacetic acid / Controle eletroquimico de herbicida em soluções aquosas : estudo da degradação do acido 2,4-diclorofenoxiacetico
In this work, the performance of the H2O2 electrogeneration process from O2 reduction on a reticulated vitreous carbon cathode was investigated. The process was also use for the oxidation of the herbicide 2,4-dichlorophenoxyacetic acid. Firstly, cyclic voltammetries were used for the identification of possible reduction reactions of the herbicide. The suppor

5. Patossistema caupi X Macrophomina phaseolina: método de detecção em sementes, esporulação e controle do patógeno. / The pathosystem cowpea x Macrophomina phaseolina: detection in seeds, esporulation and pathogen control.
Notwithstanding the specie Vigna unguiculata (L.) Walp is sufficiently rustic and adapted to the adverse conditions of the Brazilian soil and climate, its improvement is very low. Many causes have been raised in order to explain such behavior; among them the fungal diseases stand out, over all those whose pathogens are transmitted by the seeds especially the
