Abstract
Procedimiento para encapsular un agente biológico químico, caracterizado porque comprende las etapas de: (a) preparar una dispersión o solución de un agente biológico químico adecuado en un primer material formador de matriz que comprende una solución acuosa de un xantanto de polímero polihidroxi (PPX) que tiene un grado de sustitución xantato (D.S.) de 0,1 a 3, en donde la cantidad relativa de dicho PPX con respecto al agente biológico es suficiente para atrapar el agente dentro de una matriz de dicho PPX; (b) hacer reaccionar el PPX con un agente de acoplamiento elegido entre un agente oxidante adecuado, una sal soluble en agua de un ión de metal polivalente y un compuesto orgánico difuncional adecuado, a un pH de 2 a 7 aproximadamente, para formar una primera matriz insolubilizada atrapando con ello al citado agente; y (c) recuperar el agente biológico químico atrapado.
