Horretarako espektrofotometria ultramore-ikuskorra erabili da eta ioi-kromatografia erreferentziazko teknika gisa. Kimiomtetria ere erabili da, zehazki PLS-a, hipofosfitoaren edukia modelatzeko, laginetan interferentziak egon daitezkeen arren.This work explains the development of a colorimetric method to determine hypophosphite in nickel plating baths by the molybdenum blue reaction and using ultraviolet-visible spectrophometry. Ion-chromatography have been used as the reference technique. Chemometry, specifically PLS, has also been used to model the hypophosphite content, although there may be interferences in the sampleHipofosfitoa; Nikel-estaldura bainua; Zinetika; Molibdeno urdinaHypophosphite; Nickel Plating Baths; Kinetics; Molybdenum blueKimikaintroduction
