Abstract: A detection method for determining chloride ions content in sea sand includes the steps of drying sea sand to a constant weight, adding the dried sea sand to boiling deionized water, fully stirring, and standing and filtering the deionized water to obtain washed sea sand and a washed filtrate. The washed sea sand is then ground into a powder and added into deionized water and fully stirred, the deionized water then filtered to obtain a powder filtrate. Half of the washed filtrate and half of the powder filtrate is then mixed and stirred to prepare a mixed filtrate. The chloride ions content in each of the washed filtrate, the powder filtrate, and the mixed filtrate is then measured by using a silver nitrate titration method. The detection results are then analyzed and corrected to obtain the chloride ions content in the sea sand.
