Abstract

"DETERMINAçãO DAS PROPRIEDADES DE UMA SOLUçãO OU SóLIDO AO SE EMPREGAR COEFICIENTES DE RAMAN" a invenção se refere ao uso de coeficientes, produtos e funções não lineares de adsorção, emissão ou difusão da luz como variáveís em técnicas de regressão e quimiométricas padrão para predizer uma característica ou propriedade de um sólido ou líquido, o uso de uma ou mais funções não lineares dentro de um relação entre propriedades espectrais medidas e propriedades características de soluções e sólidos fornece um meio aperfeiçoado para determinar uma propriedade quando as intensidades representam estão relacionadas com componentes que são colineares ou interrelacionados devido às restrições associadas com a composição, os processos químicos, ou a estrutura molecular; ao uso de coeficientes de intensidades de pico de Raman para predizer as propriedades de uma solução ou um sólido tal como polpa que é processada com a solução; a intensidade da luz deslocada de Raman é utilizada para criar coeficientes de intensidade de pico de Raman; essas intensidades de Raman estão relacionadas com a concentração da espécie dissolvida no líquido; os espectros de Raman são corrigidos na linha base e a dispersão de uma fonte de ãgua é subtraída antes da extração das intensidades para os coeficientes de intensidades de pico de Raman;as intensidades de dispersão de Raman fornecem uma boa medida da concentração de moléculas oxigenadas pequenas; o potencial de um processo de oxidação-redução é determinado convenientemente ao se utilizar coeficientes de intensidade de pico de Raman; as moléculas pequenas e os íons complexo relevantes na indústria de papel e celulose incluem S042-, S032-, H202, CIO2, HCIO,3, silicatos, ácido acótico, HCIO3, Ciorato C103-, ácido Cloroso HCi02, Ciorito C102-, ácido Hipocioroso HCIO, Hipociorito CIO-, fosfato, nitrato, nitrítos; o método também pode ser utilizado para determinar uma propriedade relacionada com o tamanho relativo, o grau de polimerização, a ramíficação ou formação de rede de espécies de complexos ou polimerizadas; o método também pode ser utilizado para medir moléculas grandes tais como hemicelulose, extrativos e substâncias péctícas.
