摘要

Process for preparation of natural clay for use as phase sorbent and pre-filled concentrates elements and chemical species in devices.The process of construction of devices with natural clay for concentration and determination of elements and chemical species in aqueous solution of the present invention discloses the preparation process of natural clay and its use in devices, providing sorption And pre concentration of elements and chemical species. The argilominerau00eds.In particular, the montmorilonu00edta appear as materials sorventes. Alternative and low cost. The present invention reveals the process of the construction of the device with clay and its use in aqueous solutions.In a wide range of pH and ionic strength on the concentration and determination of elements and chemical species at the level of trait in liquid media, natural or artificial, such as, for example, rivers, lakes, reservoirs, the sea, swimming pools, tanks and so on.The device has a cylindrical base (1) with a lid (7) which contains in its interior a phase sorbent comprised of membranes (2) and (4) that supports a mass of argu00edlomineral (3), poruma diffusive phase which may be, for example, a polimu00e9ru00edco material in the form of hydrogel (5), a membran (6) for a device versatile, low cost, easy preparation and handling.
