    Aplicación del proceso foto-fenton solar para la recuperación del cloroformo residual obtenido luego de la realización del Ensayo de cadmio (Métodos HACH 8017) en el Laboratoirio de Control de Calidad de la Empresa Pública - Empresa Municipal de Agua Potable y Alcantarillado de Ambato (EP-EMAPA-A)

    The aim of this research was to study the recuperation of the residual chloroform obtained after the cadmium test (HACH Method 8017) in the Laboratory of Quality Control of the Empresa Pública-Empresa Municipal de Agua Potable y Alcantarillado de Ambato (EP-EMAPA-A) through the application of the Photo-Fenton solar process. The samples used contained a mixture of residue-water in 1:3 ratio. Different volumes of hydrogen peroxide (H2O2) and ferrus ion concentration [Fe2+] were applied. The optimun H2O2/Fe2+ ratio was determinated by gas chromatography analizing the chlorofotm recovered after the application of the oxidatuive process. The values corresponding the optimum ratio were 0,075 mL/27,563 mg for H2O2 and Fe2+ respectively. Reaching a percentage of chloroform area of 100,0 ± 0,00 and a probability that the sample read was constituted by chloroform of 93,45 ± 2,05. Applying this optimum ratio in the solar Photo-Fenton process, a 96,4 percent cadmium removal was achieved. When the cadmium test was run with chloroform recovered against a reference material (Trace Metals 1-WS, Fluka Analytica) a reading of 28,2 mg Cu / L was obtained, established value within the certified values of the analysis corresponding to 28,1 ± 0,4 mg Cu / L.
