English title:	CHARACTERIZATION OF A PUMICE STONE GEOPOLYMER AND ITS SELECTIVITY IN THE REMOVAL OF IONIC CONTAMINANTS
Spanish title:	Caracterizaci�n de un geopol�mero de Piedra P�mez y su selectividad en la remoci�n de un contaminante i�nico
English abstract:	Geopolymers are inorganic materials that are the product of the reaction of aluminosilicates in the presence of an alkaline activator, which promotes the dissolution of the precursor, allowing the formation of monomers that subsequently form a three-dimensional red. The various uses in which they can be implemented extend to the range of materials with adsorbent characteristics, which have been studied in recent years, with selectivity being one of the most important characteristics when performing removal in real systems, since that from it appeared, the efficiency of water decontamination for specific contaminants. The present work proposes the selectivity of a pumice-based geopolymeric material to remove ionic contaminants in wastewater, finding that the synthesized geopolymer removes up to 38% methylene blue, 25% methyl orange and 20% methyl violet in 90 min, which is indicative that the geopolymeric material has a tendency to retain the methylene blue dye in a higher proportion, this may be due to the volume of the molecule and the fact that its residual charge stabilizes the structure of the material polymeric, itself through the characterization techniques the morphological and structural change of the raw material is evidenced, which indicates that the polymerization process is carried out successfully and through the BET methodology we can observe that the average size of the pores in the material is 19 nm and can be classified as a mesoporous material
Spanish abstract:	Los geopol�meros son materiales inorg�nicos producto de la reacci�n de aluminosilicatos en presencia de un activador alcalino, el cual fomenta la disoluci�n del precursor permitiendo la formaci�n de mon�meros que posteriormente forman una red tridimensional. Los diversos usos en los que se pueden implementar se ampl�an al rango de materiales con caracter�sticas adsorbentes, los cuales han venido estudi�ndose en los �ltimos a�os, siendo la selectividad una de las caracter�sticas de mayor importancia al momento de realizar la remoci�n en sistemas reales, ya que de ella depender�, la eficiencia de la descontaminaci�n de aguas para contaminantes espec�ficos. El presente trabajo plantea el estudio de la selectividad de un material geopolim�rico a base de piedra p�mez para remover contaminantes i�nicos en aguas residuales, encontrandose que el geopolimero sintetizado remueve hasta un 38% de azul de metileno 25% de naranja de metilo y 20% de metil violeta en 90 min, lo cual es indicativo que el material geopolim�rico posee una tendencia a retener con mayor proporci�n el colorante azul de metileno, esto puede ser debido al volumen de la mol�cula y al hecho que su carga residual estabiliza la estructura del material polim�rico, a si mismo mediante las t�cnicas de caracterizaci�n se evidencia el cambio morfol�gico y estructural de la materia prima, lo cual indica que el proceso de polimerizaci�n se lleva a cabo exitosamente y mediante la metodolog�a BET podemos observar que el tama�o promedio de los poros en el material es de 19 nm pudi�ndolo clasificar como un material mesoporoso
