Abstract

PROCEDIMIENTO PARA LA DETERMINACION Y CUANTIFICACION DE LIGNINAS, QUE CONSISTE EN LA ADICION DE NO3K A UNA SOLUCION BASICA Y REDUCIDA DE LA MUESTRA, LO QUE PROVOCA UNA OXIDACION PARCIAL DE LA LIGNINA, Y TRAS SU CONDENSACION CON FLORO-GLUCINA CLORHIDRICA EN FASE LIQUIDA, PRODUCE UNA COLORACION ESPECIFICA, Y DE INTENSIDAD PROPORCIONAL A LA CONCENTRACION DE LIGNINAS PRESENTES EN LA MUESTRA. SE PREVE LA APLICACION DEL PROCEDIMIENTO A MUESTRAS EN ESTADO SOLIDO Y A MUESTRAS QUIMICAMENTE DETERIORADAS, OXIDADAS O HIDROLIZADAS. EL PROCEDIMIENTO ESTA ESPECIALMENTE INDICADO PARA EL ESTUDIO Y CONTROL DEL MEDIO AMBIENTE.
