Sorption of phenol and phenol derivatives in hydrotalcite; Sorcion de fenol y derivados de fenol en hidrotalcita

Abstract

One of the main problems in Mexico and in the World is the waste water pollution of a great variety of industrial processes by organic compounds. Among those ones the phenol compounds which are highly toxic, refractories (to the chemical degradation) and poorly biodegradable. This is due in a large extent to the problem created by the accelerated increase in the environmental pollution in the cities and industrial centers. The phenol compounds are used in a great variety of industries such as the production of resins, plasticizers, antioxidants, pesticides, colourings, disinfectants, etc. These phenol compounds are specially harmful, since they have repercussions on the flora of plants of biological treatment of water affecting its operation. The main objective of this work is to evaluate the capacities of phenol detention and its derivatives in an hydrotalcite type compound and diminishing with it the presence in water, in this case, of solutions prepared in the laboratory. In order to analyse this elimination process was used a methodology based in the carrying out in batch experiments and in the elaboration of a sorption isotherm. It is worth pointing out that this work was realized at laboratory scale, at relatively high phenol concentration ratio.  More>>

It is worth pointing out that this work was realized at laboratory scale, at relatively high phenol concentration ratio. With the obtained results when the sorption properties are evaluated the calcined hydrotalcite (HTC) for detaining phenol and p-chloro phenol it was observed that it is detained greater quantity of p-chloro phenol than phenol in the HTC. The detention of these phenol compounds in the HTC is due to the memory effect by the hydrotalcite regeneration starting from the oxides which are formed by the burning material. (Author)}
