Optimum Chemical

Polyethylene terephthalate (PET) bottles are being used in our daily life and consequently go to the landfills after their use. Additionally, virgin PET resins are produced from nonrenewable resources, such as fossil fuels, whose reserves are depleting continuously. Therefore, to maintain ecological and environmental balances as well as for sustainable development, post-consumer PET (pcrPET) bottles should be recycled. Among many recycling processes, mechanical recycling of pcrPET is attractive due to lower cost involvement. One of the most crucial and important processes of mechanical recycling is hot washing for contaminants removal. Hot washing uses a cleaning solution made of caustic soda (NaOH) and detergent at elevated temperature. In this paper, caustic soda and FORYL LFO (FLO) detergent doses were changed gradually to investigate effective contaminants removal through colorimetric study. Finally, concentration vs. absorbance graphs from colorimetric study suggests that 2% NaOH and 2% FLO detergent is the optimum chemical dose at hot washing for pcrPET recycling.

El presente estudio da a conocer los resultados de los análisisno invasivosde colorimetría y espectroscopía de reflectancia visible llevados a cabo por primera vez sobre cinco ejemplos de escultura románica en mármol del Museo Arqueológico Nacional (Madrid) de procedencia gallega y leonesa. En concreto se han analizado dos columnas de San Paio de Antealtares (Santiago de Compostela), un parteluz de Vigo, y dos ejemplos procedentes del monasterio de San Benito de Sahagún (León).The present study reveals the results of the non-invasive analysis of colorimetry and visible reflectance spectroscopy, carried out for the first time to five examples of Spanish Romanesque marble sculpture from the National Archaeological Museum (Madrid, Spain) of Galician and Leonese origin. Specifically, two columns of San Paio de Antealtares (Santiago de Compostela), a mullion from Vigo, and two examples from the monastery of San Benito de Sahagún (León) have been analyzed.
