    Abstract: PROBLEM TO BE SOLVED: To provide a method for removing metal from an acid and, more particularly, to provide a method for removing a metal from an acid by using an aluminum-deficient zeolite.
    SOLUTION: The aluminum-deficient zeolite is obtained by washing a natural or synthetic zeolite with a strong acid such as sulfuric acid to dissolve and remove an aluminum content. A metal is removed from an acid by membrane separation by forming a film of the aluminum-deficient zeolite onto a porous ceramic substrate or by packing the granules of the zeolite into a packing tower and passing the acid containing the metal through the packed granules. According to these methods, it is possible to obtain an acid-free pure metal.

    Abstract: PROBLEM TO BE SOLVED: To provide an advanced fluorine treatment equipment for reducing the concentration of fluorine in wastewater to an environmental standard or less in an industrially efficient manner.
    SOLUTION: The fluorine component (F) in a fluorine compound to be removed is adjusted under a condition such that an added and/or mixed calcium component (Ca) is 5 or more in a Ca/F molar ratio and that added and/or mixed phosphorus component (P) is 3 or more in a P/F molar ratio, and is adjusted with a flowmeter and/or a pH meter to remove fluorine in wastewater as a hardly soluble substance from CaF2.

    IPC: C09K21/12

    Abstract: PROBLEM TO BE SOLVED: To provide an unusually hardly soluble melamine polyphosphate free from the problem that the conductivity increases when allowed to absorb moisture.
    SOLUTION: The hardly soluble melamine polyphosphate can be obtained by washing an ammonium polyphosphate with water or an organic solvent to remove soluble matters in the melamine polyphosphate. It is desirable that water or an organic solvent is heated to 40°C or higher for washing. It is more effective to apply steam during washing or after washing. It is desirable that the organic solvent used is adjusted to pH 3 or lower.

    Abstract: PROBLEM TO BE SOLVED: To provide a linear polyphosphate of a higher-degree polymerization, which is useful as a biomaterial, an electronic material, optical ceramics, pharmaceuticals, and a raw material for pharmaceuticals.
    SOLUTION: An octapolyphosphate, which is a new polyphosphate with a structure expressed by the formula (1), is provided. The octapolyphosphate is obtained by selectively ring-opening a cyclooctaphosphate by hydrolyzing it with a hydroxide of an alkali metal, etc. In formula (1), M denotes at least one kind of alkali or alkaline earth metal, provided that in the case of an alkaline earth metal, the number of moles of M is 1/2.

    Abstract: PROBLEM TO BE SOLVED: To provide a carbonizing agent having improved affinity with a resin, wherein a resin compound does not bleed under high temperature and high humidity.
    SOLUTION: The carbonizing agent with improved affinity with the resin can be obtained by bringing the carbonizing agent, which is dispersed in an organic solvent and/or water, into contact with a melt or dissolved surfactant.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for separating/removing fluorine efficiently from a liquid containing a fluorine compound and a metal without increasing the pH of the liquid and lowering the fluorine concentration of the liquid containing the separated fluorine below the environmental standard value.
    SOLUTION: Phosphoric acids and/or a phosphorus compound is added to the fluorine compound-containing liquid treated by diffusion dialysis or electrodialysis instead of a calcium compound or together with the calcium compound, which is then made to pass through a packed column packed with particles of calcium phosphate.
