摘要

Method of estabilizau00c7ao of Schiff's reagent in various vehicles, Schiff's reagent immobilized on solid matrix, process of impregnau00c7u00c3o this reagent, method of determining analytical samples based on the use of the Schiff's reagent kit for determinau00c7u00c3 stabilized. The especially methanol and formaldehyde in commercial products and their applications.The present invention relates to a method of stabilization of the Schiff's reagent in several vehicles (liquid or solid), useful in the colorimetric determination of the presence or not of specific compounds in a sample, especially aldehydes and alcohols.Obtaining this reagent stabilized, especially the immobilized on solid matrices, such as oxides of metals and non metals, cellulose materials, polymers, allow the analysis in the field or places of interest, in addition to facilitate operationally the analyses on usuu00e1r Two common or methodologies that use this reagent is prepared in a conventional manner.Another aspect is the development of a colorimetric analysis method of qualitative and semi quantitative dessess compounds, and to a kit for analytical determination in the field, especially methanol and / or formaldehyde in commercial products, such as fuel, solvent liquid and beverage. Ou00f3licas, as well as the analysis of formaldehyde in cleaning products, cosmetics and personal hygiene and sanitizing.And yet, its applications.
