RESIDUAL TLC SILICA GEL: RECUPERATION PROCESS, CHARACTERIZATION AND APPLICATION
The use of silica gel intensively in chemical laboratories has a high cost, and generate a significant amount of solid waste contaminated with organic compounds. In this sense, the search for effective methods to reduce the impacts that this material can cause to the environment, has been a motivating factor for many researchers, since its use has grown extensively in scientific research segment. So, the present work shows the recuperation process, characterization and application of the Silica Gel 60G, a adsorbent used in the preparation of Thin Layer Chromatography. According to the results, the proposed methodology was able to recover the residual silica gel, making it possible to be reused in the process of separation and/or purification of organic substances in a practical manner and with reduced environmental impact.
