Methods used to determine the zeta potential of colloids in wastewater

Jhonny Valverde Flores


Water is the vital element in the daily life of man and the value of his treatment is to look for the sustainability of the planet and to preserve human life. The study is descriptive and comparative. The objective was to propose the most appropriate method for the zeta potential determination of colloids in wastewater. The operational procedure requires the knowledge of more related parameters, which implies greater analysis and therefore greater economic investment. The methods described are: Electrophoresis, Electroosmosis, Flow potential and sedimentation potential. Of the four methods for the determination of zeta potential in wastewater it is concluded that the electrophoresis method is the most used until now, which is used in different areas in greater or lesser scale, as in the application of solutions with different types of pollutant, unlike the other methods mentioned above. The electrophoresis has varied designs in such a way that it can be built manually and be applicable from small experiments with more accessible and easy-to-get materials, allowing to vary the construction investment of the equipment according to the scale of the work in which it is to be applied this method.
