“…The design and characterization of electrochemical cells currently moves from empirical design to the application of models of hydraulics, mass transfer, and their impact on current distribution and potential. Our group has implemented strategies to design and scale, in an efficient and robust way, electrochemical reactors (from the laboratory to industrial reactors of large volume of operation) [22] for various applications ranging from the recovery of gold and silver dusts [13], and the leaching of concentrates less polluting than using cyanide, to the treatment of effluents from the electroplating [23] and textile industries [24], effluents with high fat and oil content, and currently, with arsenic [25], among others. The efficiency and selectivity of these reactors allows them to be coupled with biological reactors in a novel way [26].…”

Abstract. The recognition as emeritus researcher granted by the Mexican Council of Science and Technology a year ago (2020) appeared as a reminder of the beginning of my career of the challenges, friendships and experiences lived at the extrema during these years up to now. Though I am grateful for the opportunity granted by the Journal of the Mexican Chemical Society to write this article, summarizing all the experiences and teachings in a single perspective article would be a titanic task. Nevertheless, I am committed to highlighting some key moments from my journey so far. It is my hope that this manuscript will inspire and motivate the next generation of electrochemistry researchers and commemorate the unforgettable experiences shared with my students, colleagues, and friends. Resumen. El reconocimiento como investigador nacional emérito que me fue otorgado por el Consejo Nacional de Ciencia y Tecnología hace un año (2022) ha detonado el reencuentro con las experiencias vividas al inicio de mi carrera que comprenden retos, amistades y múltiples experiencias, vividas con gran intensidad desde esos días (1984) hasta el día de hoy. Agradezco la oportunidad que me ha concedido la Sociedad Química de México de escribir este artículo, resumir todas las experiencias vividas y aprendizajes adquiridos en este artículo de perspectiva ha sido una labor titánica. De esta manera se describen los momentos claves que fueron apareciendo en mi carrera científica y que forjaron mis conocimientos y habilidades. Deseo que este escrito inspire y motive a la siguiente generación de investigadores electroquímicos y que así mismo, sea un reconocimiento a las experiencias inolvidables compartidas con mis estudiantes, colegas y amigos.

“…The electrorecovery of silver from rinse water (1.3 g/l) from cyanide media was evaluated using laboratory scale RCE. Using two rotating cylinder electrode reactors: bench scale and pilot plant, the electrorecovery of Ni from synthetic and real electroplating rinse effluents (1.2 g/l) Ni 2+ was investigated [89]. Because of uniform flow produced at low rotation speed, the controlled mass transport rate, and the uniform current distribution, the RCE is appealing for turbulent studies of metal recovery and electrolytic investigations [90].…”

Electrochemical technology has a very broad range of environmental protection applications and generally aims to improve the environment in a number of ways. Environmental electrochemistry is a novel field of study that has appeared recently. Environmental electrochemistry is the use of electrochemical methods to remove poisons from industrial wastewater before it is discharged into the environment. The main goal of this article is to provide a full review of the choices of electrochemistry and electrochemical technology to clean the environment. We cover industrial applications for the electrochemical removal of heavy metals from diluted solutions. A careful survey of the various electrode types and cell designs like rotating cylinder electrode cells, Swiss-roll cells, fixed packed bed cells, fluidized bed cells, and spiral wounded steel electrodes is presented. All of these cells are used to extract toxic heavy metals from industrial solutions and waste liquids. These cells' activity is governed by a number of operating factors. These operational parameters that control reactor performance and efficiency are reviewed. We cover the advantages and disadvantages of various techniques for electrochemical recovering metals and cleaning up pollution is reviewed. The use of bench-scale cells from Central Metallurgical R & D Institute (CMRDI) researchers in this research proves the following: Copper refiners' solutions were reduced using packed column electrode cells, and Swiss-roll cells. Toxic chromium was electrochemically removed from electroplating and tanning solutions using rotating cylinder electrode cells. In a three-dimensional cell, the electro-removal of cadmium employing a spiral-wound steel electrode from the solution was evaluated.
