English title:	Characterization of the plant species Opuntia ficus indica cultivated in Boyac� - Colombia as potential corrosion inhibitor.
Spanish title:	Caracterizaci�n del Nopal como especie vegetal cultivada en Boyac� - Colombia como potencial inhibidor de corrosi�n
English abstract:	Corrosion inhibitors have generated a remarkable effectiveness in the protection of the corrosive reaction to the different environmental conditions of steels, especially those destined to engineering functions. Likewise, it is necessary the production of raw materials corresponding to the search for environmental sustainability. Specifically, cacti plant species. However, despite its wild growth throughout the Colombian territory, it is little used and its physicochemical behavior is not clear. Therefore, this research proposes the development of a corrosion inhibitor extracted from the plant species Opuntia ficus indica grown in Boyac�, in order to establish its use as a potential corrosion inhibitor, by understanding the chemical phenomena present. For this purpose, the species was initially characterized botanically to control the components and later a bromatological analysis was performed to define compounds that establish potential physicochemical phenomena and then Thermogravimetric Analysis was carried out. Initially, the results show that approximately 95% of the plant is composed of water, which is related to the high potential for electrostatic interaction. This was evaluated by infrared and Raman spectroscopy analysis, which allowed the semiquantitative evaluation of the presence of hydroxyl and carboxyl functional groups that compose polysaccharide chains, which corresponds to approximately 85% of the total composition according to the bromatological analysis. This is related to the results of the zeta potential and the generation of a large interface that allows reducing the electrochemical reactions causing corrosive�effects.
Spanish abstract:	Los inhibidores de corrosi�n han generado una efectividad notable en la protecci�n de la reacci�n corrosiva ante las diferentes condiciones ambientales de los aceros, especialmente los destinados a funciones ingeniarles. Asimismo, es necesario la producci�n de materias primas correspondiente a la b�squeda de la sostenibilidad ambiental. Espec�ficamente las especies vegetales cact�ceas. Sin embargo, pese a su crecimiento de forma silvestre en todo el territorio colombiano, esta es poco utilizada y no es claro el comportamiento fisicoqu�mico. Por lo anterior, la presente investigaci�n plantea el desarrollo de un inhibidor de corrosi�n extra�do de la especie vegetal Opuntia ficus indica crecida en Boyac�, con el fin de establecer su uso como potencial inhibidor de corrosi�n, mediante el entendimiento de los fen�menos qu�micos presentes. Para esto inicialmente se caracteriz� bot�nicamente la especie para el control de componentes y posteriormente un an�lisis bromatol�gico para definir compuestos que establezcan potenciales fen�menos fisicoqu�micos y posteriormente se realizaron An�lisis Termogravim�tricos. Inicialmente, los resultados muestran que aproximadamente el 95% de la planta est� compuesta de agua, lo cual se relaciona con el alto potencial de la interacci�n electrost�tica. Esto se evalu� mediante an�lisis de espectroscopia infrarroja y Raman, lo que permiti� la evaluaci�n semicuantitativa de la presencia de grupos funcionales hidr�xido y carboxilo que componen cadenas de polisac�ridos, que corresponde aproximadamente al 85% de la composici�n total seg�n el an�lisis bromatol�gico . Lo anterior se relaciona con los resultados del potencial zeta y la generaci�n de una gran interfase que permite reducir las reacciones electroqu�micas causante de efectos�corrosivos.
