Abstract

KIT PARA DETERMINACION DEL CLORO LIBRE Y COMBINADO EN AGUAS BASADO EN UN METODO PARA EL ANALISIS DE CLORO LIBRE Y COMBINADO EN AGUAS QUE SE CARACTERIZA PORQUE UTILIZA COMO REACTIVO CROMOGENO 3.3", 5.5" -TETRAMETILBENZIDINA (TMB)- DISUELTA EN ACIDO CLORHIDRICO 0,5 MOL/L Y ETANOL AGUA. PARA PREPARAR LA ESCALA DE CALIBRADO SE EMPLEAN DISOLUCIONES DE TROPEOLINA 0 DE 0,52 A 21 MG/L QUE SE CORRESPONDEN CON LAS INTENSIDADES Y MATIZ DE COLOR QUE DAN CONCENTRACIONES DE CLORO DE 0,05 A 2 MG/L AL REACCIONAR CON TMB. LA ESCALA SINTETICA DE TROPEOLINA 0 TIENE UNA ESTABILIDAD DE 5-6 MESES A TEMPERATURA AMBIENTE. EL NUEVO KIT QUE SE QUIERE PATENTAR PARA LA DETERMINACION DE CLORO POR COMPARACION VISUAL DE MUESTRA TMB Y ESCALA DE TROPEOLINA, NO EMPLEA RADIACTIVOS TOXICOS.
