Method for detecting sodium content of hydrogenated rosin

The invention discloses a method for detecting the sodium content of hydrogenated rosin, and belongs to the technical field of analysis and detection method. According to the method, through sodium contents of a series of sodium standard solutions and detected corresponding light absorption values, a unary linear regression equation representing the relationship between the light absorption value and sodium concentration can be obtained through calculation; then a hydrogenated rosin sample is dissolved to prepare a solution, the light absorption value of the solution is measured, and then the measured light absorption value is substituted into the unary linear regression equation to calculate the sodium content of the solution. The provided method can measure the sodium content of hydrogenated rosin by using atomic absorption spectrum, the shortages of conventional national sodium detection method of hydrogenated rosin are overcome; through the provided method, the sodium content of hydrogenated rosin can be
