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.

Abstract: The present invention relates to a detection method for determining chloride ions content in sea sand, which is performed in the steps as follows: drying sea sand to a constant weight, adding the dried sea sand to boiling deionized water, and fully stirring, standing and filtering the deionized water to obtain washed sea sand and a washed filtrate; then grinding the washed sea sand into powder, adding the powder into deionized water, fully stirring and filtering the deionized water to obtain a powder filtrate; next, taking half of the washed filtrate and half of the powder filtrate, mixing and stirring the two to prepare a mixed filtrate; and measuring the chloride ions content in each of the washed filtrate, the powder filtrate and the mixed filtrate by using a silver nitrate titration method; finally, analyzing and correcting detection results to obtain the chloride ions content in the sea sand.
