It is on the World Health Organization's List of Essential Medicines. Activated carbon will not prevent these chemicals from being absorbed into the human body. However, activated charcoal shows no effect on intestinal gas and diarrhea, and is, ordinarily, medically ineffective if poisoning resulted from ingestion of corrosive agents, boric acid, petroleum products, and is particularly ineffective against poisonings of strong acids or bases, cyanide, iron, lithium, arsenic, methanol, ethanol or ethylene glycol. Tablets or capsules of activated carbon are used in many countries as an over-the-counter drug to treat diarrhea, indigestion, and flatulence.
Activated carbon treatment removes such impurities and restores plating performance to the desired level.Īctivated carbon is used to treat poisonings and overdoses following oral ingestion. Their excessive build up can adversely affect plating quality and physical properties of deposited metal. Due to passage of direct current and electrolytic reactions of anodic oxidation and cathodic reduction, organic additives generate unwanted breakdown products in solution. A variety of organic chemicals are added to plating solutions for improving their deposit qualities and for enhancing properties like brightness, smoothness, ductility, etc. For example, it is the main purification technique for removing organic impurities from bright nickel plating solutions. One major industrial application involves use of activated carbon in metal finishing for purification of electroplating solutions. 6 Modification of properties and reactivityĪctivated carbon is used in methane and hydrogen storage, air purification, capacitive deionization, supercapacitive swing adsorption, solvent recovery, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in respirators, filters in compressed air, teeth whitening, production of hydrogen chloride and many other applications.1.6 Distilled alcoholic beverage purification.When derived from coal it is referred to as activated coal. These bulk sources are converted into charcoal before being 'activated'. Further chemical treatment often enhances adsorption properties.Īctivated carbon is usually derived from waste products such as coconut husks waste from paper mills has been studied as a source. An activation level sufficient for useful application may be obtained solely from high surface area. Charcoal, before activation, has a specific surface area in the range of 2.0 - 5.0 m 2/g. Activated is sometimes replaced by active.ĭue to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and has a surface area that is much larger than the kernels. It is processed (activated) to have small, low-volume pores that increase the surface area available for adsorption (which is not the same as absorption) or chemical reactions. Todo ello desde una concepción integral del ser humano.Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses.
En lugar de instruir o aconsejar al cliente, el trabajo del coach co-activo consiste en hacerle preguntas que le ayuden a esclarecer sus objetivos, escucharle y darle los recursos necesarios para que emplee las herramientas y la creatividad que ya posee.
Esta obra ha sido la referencia de múltiples programas de coaching de desarrollo profesional y empresarial, así como de miles de personas que han querido mejorar sus habilidades comunicativas y de liderazgo.Įl coaching co-activo se basa en la premisa de que la persona es naturalmente creativa, autónoma y que posee grandes recursos, lo cual le permite encontrar sus propias respuestas a los retos a los que se enfrenta en su vida personal y profesional. Cuando este libro, pionero en su campo, fue publicado por primera vez en 1998, sentó las bases de lo que se convirtió en un fenómeno cultural y empresarial que ayudó a introducir el coaching en el ámbito profesional.Ĭoaching co-activo se ha traducido a más de diez idiomas y ha vendido más de 100.000 ejemplares en inglés.
