Abstract

PROCEDIMIENTO PARA LA ENCAPSULACION DE UN AGENTE QUIMICOBIOLOGICO INSOLUBLE EN AGUA. CONSISTE EN PREPARAR UNA DISPERSION DEL AGENTE GIOLOGICO INSOLUBLE EN AGUA EN UN MATERIAL FORMADOR DE MATRIZ QUE CONTIENE UNA PARTE ACUOSA QUE TIENE UN ALCOXIDO DE METAL ALCALINO; HACER REACCIONAR EN LA FASE ACUOSA DE LA PASTA EL ALCOXIDO CON UN CATION BIVALENTE, TAL COMO CALCIO,ESTRONCIO O BARIO. PARA FORMAR UNA MATRIZ INSOLUBLE QUE CONTIENE EL AGENTE BIOLOGICO Y SEPARAR ESTA DE LA FASE ACUOSA. TIENE APLICACIONES PARA EL ENCAPSULADO DE HERBICIDAS, INSECTICIDAS. FUNGICIDAS, FUMIGANTES. FERTILIZANTES, ETC.
