    Abstract: The present invention relates to an undivided electrochemical cell for ferrate(V) and/or ferrate(VI) continuous production, comprising: a housing defining an undivided chamber, the housing having one electrolyte inlet; an iron-containing anode in the chamber; a cathode in the chamber; an electrolyte in the chamber, a screen between the anode and the cathode in the chamber, defining an anode compartment and a cathode compartment; at least two outlets, one for the anode compartment and one for the cathode compartment; and a variable direct current power supply operatively connected to electrochemical cell; wherein the direct current power supply is capable of producing a continuously and automatically varied variable direct current voltage between the anode and the cathode to form the ferrate(V) and/or ferrate(VI), the variable direct current voltage varying between a maximum voltage (Vmax) and a minimum voltage (Vmin), the Vmin is greater than 0 and is a voltage to ensure that formation of an oxide film on a surface of the anode is depressed so that passivation of the anode is substantially avoided; wherein the anode is not a gas diffusion electrode, and wherein the anode and cathode are substantially vertical.

    Abstract: Aparato, materiales y procedimientos para eliminar amoniaco de fluidos utilizando hidróxidos metálicos (por ejemplo, hidróxido de zinc) y medios de carga metálica (por ejemplo, resinas intercambiadoras de iones cargadas de zinc); los hidróxidos metálicos y los medios de carga metálica pueden regenerarse con un ácido débil (pK{sub,a} entre 3 y 7). Alternativamente, se elimina el amoniaco de fluidos utilizando H{sub,2}SO{sub,4} y ZnSO{sub,4} y medios de carga metálica; los medios de carga metálica pueden regenerarse con H{sub,2}SO{sub,4} y ZnSO{sub,4}; el amoniaco que contiene H{sub,2}SO{sub,4} y ZnSO{sub,4} puede concentrarse si fuera necesario para formar cristales de (NH{sub,4}){sub,2}SO{sub,4}uZnSO{sub,4}u6H{sub,2}O (sulfato hexahidrato de amoniaco y zinc). Los cristales se eliminan del licor madre y se calientan hasta temperaturas que sobrepasan los 200ºC liberando NH{sub,3} y H{sub,2}O vapor por descomposición de los cristales.
