Spectroscopic evaluation of charcoal derived humic-like acid. Author(s): FERREIRA, E. J. B.; BROCCHI, E. A.; MAURICIO, G. M.; NUNES, R. A.; BENITES, V. de M. The aim of this work is to study the suitability of using different charcoals in order to produce humic-like acid. Fluorescence and UV-visible spectroscopy were applied to evaluate the humidification... ... Repository: BDPA Publication year: 2008
Synthesis, Vibrational Spectroscopic and Thermal Properties of Oxocarbon Cross - Linked Chitosan. Author(s): SOUZA, N. L. G. D.; SALLES, T. F.; BRANDAO, H. de M.; EDWARDS, H. G. M.; OLIVEIRA, L. F. C. de In this work specimens of chitosan which have been cross-linked covalently and ionically with different oxocarbon and pseudo-oxocarbon anions have been synthesised and characterized using infrared and... ...

EPR and DRIFT spectroscopic characterization of humic fractions during composting of sawdust and paper mill sludge. Author(s): MAIA, C. M. B. de F.; FUKAMACHI, C. R. B.; PICCOLO, A.; MANGRICH, A. S. The spectroscopic characteristics (DRIFT, UV-visible and EPR) of humic fractions were studied during composting of sawdust and paper mill sludge. Infrared spectroscopy reveals a compost rich in hydrox... ... Repository: BDPA Publication year: 2012
Spectroscopic investigation on the effects of biochar and soluble phosphorus on grass clipping vermicomposting. Author(s): NOVOTNY, E. H.; BALIEIRO, F. de C.; AUCCAISE, R.; BENITES, V. de M.; COUTINHO, H. L. da C. Seeking to evaluate the hypothesis that biochar optimises the composting and vermicomposting processes as well as their product quality, we carried out field and greenhouse experiments. Four grass cli... ... Repository: BDPA Publication year: 2022
