Mineralogical analysis with the firing temperature of limestone and clay mixture from Dominican Republic using Mössbauer spectroscopy and X-ray powder diffractometry
(Springer Link, 1991)
The study of a limestone and clay mixture using Mössbauer spectroscopy, and X-ray powder spectrometry (XRD) for different firing temperatures are presented. This type of mixture is used in raw minerals in order to obtain ...
Mössbauer study on indigenous ceramics in La Isabela City, Dominican Republic
(Springer Link, 1990)
The following study deals with the determination of the firing temperature of some of the ceramics found in La Isabela City, Dominican Republic, first settlement of the Spaniards in the New World. These ceramics were ...
Performance of the parallel plate avalanche counter (PPAC) for improving the depth profile of conversion electron Mössbauer spectroscopy (CEMS)
(Journal of Radioanalytical and Nuclear Chemistry, 1991)
The parallel plate avalanche counter (PPAC) built in our laboratory was used to measure the CEM spectra of iron electrodeposited over a steel substrate. The electron counter was operated with ketone gas inside the ionization ...
Mössbauer and X-ray fluorescence study of sediments from Samana Bay, Dominican Republic
(Journal of Radioanalytical and Nuclear Chemistry, 1995-08)
The chemical state of iron in sediments collected from Samana Bay has been determined by Mössbauer spectroscopy. The Mössbauer spectra were composed of two paramagnetic doulets, which correspond to high=spin ferric and ...
Determination of traces of heavy metals in estuarine waters of Barbacoas Bay, Colombia, by X-Ray fluorescence spectrometry
(1998-12-04)
An evaluation of metal contamination in estuarine waters and shrimp culture systems was conducted using two analytical processes: soluble metals were examined by radioisotope x-ray fluorescence spectrometry (RIXRF) and ...
