Method for measuring polyvinyl alcohol content in water
ActiveCN101303310ATest data is stableBoric acid-iodine spectrophotometry is stable and reliableMaterial analysis by observing effect on chemical indicatorColor/spectral properties measurementsObservational errorWater quality
The invention discloses a method for measuring polyvinyl alcohol content in the water. An excessive sulfuric acid is added under neutral heating condition (60-90 DEG C.) to remove starch having interference to the measurement by hydrolysis, and the excessive acid reacts with the polyvinyl alcohol in the sample to generate an ester in the mean time. In presence of boracic acid, the polyvinyl alcohol and the ester generated by reaction of the polyvinyl alcohol and the sulfuric acid can both react with a boracic acid - iodine - potassium iodide solution to produce a stable blue-green complex compound, and an absorbency is measured by a spectrophotometer at a point of a special wavelength of 645nm. A standard work curve is drawn according to the linear relation between the absorbency and the concentration of the reactor, thus the concentration of the sample can be known by checking the drawn standard curve after the sample measurement. The invention controls measurement error within the range of 5%, and the measurement result is stable and accurate, which makes the invention a feasible method for measuring polyvinyl alcohol concentration in the printing waste water.
