    摘要： THE INCORPORATION OF SMALL AMOUNTS OF LITHIUM ION INTO A SOLUTION OF A HEAVY METAL SEQUESTERING AGENT OF THE FORMULA:

    HO-P(=O)(-OH)-C(-R)(-OH)-P(=O)(-OH)2

    WHEREIN R IS A LOWER ALKYL RADICAL HAVING FROM 1 TO 5 CARBON ATOMS, INHIBITS THE FORMATION OF THE WHITE PRECIPITATE CHARACTERISTICALLY PRODUCED WHEN SEQUESTRANTS OF THIS TYPE ARE USED TO SEQUESTER IONS OF HEAVY METALS SUCH AS CALCIUM. ALKALI METAL, AMMONIUM AND ETHANOLAMINE SALTS OF COMPOUNDS OF THE ABOVE FORMULA AND MONO AND DIALKYL ESTERS THEREOF WITH METHANOL, ETHANOL, PROPANOL AND BUTANOL ALSO PROVIDE USEFUL SEQUESTERING AGENTS.
