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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection method for determining content of chlorine ions in marine sand","description":"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, a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11940431","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
