Resumen
Se propone la caracterización de nanoburbujas de oxígeno en soluciones salina de NaCl con el fin de explorar la concentración y tamaño por medio de saturación de oxígeno en la solución, y por procesos de cavitación para así caracterizar los diferentes tamaños y los niveles de agregación. Se cambian el pH de la solución, la temperatura y observando el proceso a diferentes tiempos. El método fundamental utilizado es la cavitación. El procedimiento para conseguir las nanoburbujas será a una temperatura predeterminada, inyectándole oxígeno a la solución a través de un medio difusivo, por rotación, de tal manera que se distribuya homogéneamente en la solución para la creación de las nanoburbujas. Al final la solución obtenida se sometió a varios muestreos a diferentes tiempos para observar cambios en las nanoburbujas. La caracterización de la solución se realizó mediante la técnica dispersión de luz dinámica (DLS) para observar el tamaño. La concentración se sometió a un proceso semicuantitativo teniendo en cuenta la concentración de partículas patrón y la tasa de conteo por segundo del dispositivo. Adicionalmente se medió el Potencial para tener una medida sobre la agregación y estabilidad de las nanoburbujas, este procedimiento se realizó a diferentes temperaturas y pHs.
Abstract Characterization of nanobubbles of oxygen NaCl saline solution in order to explore the concentration and size by means of oxygen saturation in the solution by cavitation processes is proposed in order to characterize different sizes, little aggregation capacity changing the pH of the solution, temperature and observing the process at different times. The basic method is cavitation, the procedure for obtain the nanobubbles is at predetermined temperature by injecting oxygen into the solution through a diffusive medium and spin evenly around the solution to create nanobubbles. At the end the solution obtained is subjected to several samples at various times to observe changes in nanobubbles. Characterization of the solution is performed by the technique of dynamic light scattering (DLS) to observe size. The concentration was submitted by a semiquantitative process considering particle concentration pattern and the count rate per second of the device, additionally the potential is measured to have a measure of aggregation and stability of nanobubbles, this procedure was carried out at different temperatures and pH.
