| 中文摘要: |
| This paper first presents a new potassium reagent and efficient enrichment agent for direct recovery of potassium from seawater,i.e.,1,2,4,5-tetrahydroxybenzen -O,O',O",O'"-tetraacetic acid (TTAH4).The synthetic method of TTAH4,its enrichment behaviour for potassium ion in low concentration solution and seawater,and the chemical structure of its corresponding potassium salt have been investigated.A mechanism which caused the uptake of potassium ion is suggested.Elementary analysis and IR-spectrum determination of the potassium salt proved correct evidence for a polynuclear complex,i.e., (TTAH3K)n.Thus,the mechanism which caused the uptake of potassium ion may be interpreted in terms of the formation of polynuclear chains as a continual sandwich type coordination complex. |
