Abstract: A method for analysis of the SiO2 concentration in an electrolyte for plasma electrolytic oxidation and a method for life extension of an electrolyte using the same are provided to supplement an accurate amount of SiO2 into the electrolyte by promptly analyzing Si anions polymerized in an electrolyte in which a plasma electrolytic oxidation process is carried out. A method for analysis of the SiO2 concentration in an electrolyte for plasma electrolytic oxidation comprises: a step(a) of preparing a plurality of electrolyte samples having different SiO2 concentrations; a step(b) of obtaining a calibration line showing the change of plasma anode voltage relative to the change of the SiO2 concentration in the electrolyte by measuring respective plasma anode voltages of the plurality of electrolyte samples; a step(c) of measuring a plasma anode voltage of an electrolyte collected in the same conditions as the step(b) by collecting an electrolyte on which an actual plasma electrolytic oxidation process is conducted; and a step(d) of obtaining a current concentration of SiO2 that is not polymerized in the actual plasma electrolytic oxidation process-performed electrolyte by comparing the calibration line obtained in the step(b) with the voltage measured in the step(c).
