摘要： PROBLEM TO BE SOLVED: To efficiently separate an object ion from a mutli-ion solution under selective and competitive conditions by allowing a specific compound having an exchangeable or ionizing proton forming part of a large ring compound having a liphophlic group combined with the molecule to contact with the object ion to from a complex. SOLUTION: In the case of separating the selected ion from plural ions in the multi-ion solution, the compound selected from a group composed of formula I to formula III forms the complex with the selective ion. Where, in formula I, (n) expresses the integers of 1-4 and R expresses C6-18 H13-37 , in formula II, (n) expresses the integers of 1-3 and R expresses C6-18 H13-37 and in formula III, X expresses O or Si, (n) expresses the integers of -1 to 3 and R expresses C6-18 H13-37 . The multi-ion solution is brought into contact with the compound under the condition of removing the selected ion from the mutli-ion solution. As a result, the object ion is efficiently separated from the mutli-ion solution under the selective and competitive conditions.

摘要： PURPOSE: To efficiently recover a quinolone carboxylic acid derivative from a waste liquid by bringing the waste liquid containing quinolone carboxylic acid derivative into contact with a non-polar porous synthetic adsorbent to selectively adsorb the derivative, and subsequently eluting the adsorbed derivative. CONSTITUTION: A waste liquid containing a quinolone carboxylic acid derivative of formula I or II (R is H, a 1-4C lower alkyl; R is a 1-4C lower alkyl, a 3-6C cycloalkyl, etc., which may be replaced with one or more of hydroxyl groups or halogen groups; R is a halogen, amino, etc.; R is a halogen; R is H, amino, hydroxyl, an alkyl, etc.; X is O atom, methylene) is brought into contact with a non-polar porous synthetic resin adsorbent preferably in an automatizable column method to selectively adsorb the derivative, and the adsorbed derivative is subsequently eluted to recover the derivative. The adsorption temperature is preferably 0-120 deg.C preferably 30-70 deg.C. Water, an acid, an alkali, etc., is preferably used as the elution solvent.

摘要： PURPOSE: To easily isolate L-proline used in the areas of foods, medicines and cosmetics, in a high purity and yield by adsorbing and eluting the same at a specific temperature by an ion exchange chromatography using a specific ion exchanging resin from the mixture solution of amino acids. CONSTITUTION: This method for isolating L-proline comprises adsorbing and eluting L-proline from the mixture solution of amino acids containing L-proline as a major component by an ion exchange chromatography using H -type strongly acidic cation exchanging resin (e.g. a gel-type) at an operating temperature of 40-80 deg.C, and further if necessary treating the eluted solution containing mainly L-proline by an OH-type strongly basic anion exchanging resin to remove acidic amino acids from this eluted solution to isolate the objective L-proline.

摘要： PURPOSE: To provide a filter device in which not only filtering of an image- forming solvent can surely be performed, but also, when clogging occurs, it can be recognized easily and filtering material is easily replaced at low cost, and which can be achieved by a small construction. CONSTITUTION: This filter device 10 comprises a case 12 consisting of a housing 14 and a transparent cover 16 and divided into two parts; a cartridge 34; and a cap 44 secured to an inserted portion 60 while exposing the cover 16. Then replacing only the cartridge 34 is made possible, the cartridge is made visible from the outside, and the device is prevented from increasing in size along the direction of its axis.

摘要： PURPOSE:To provide a separating method capable of separating phenol in a nonaqueous solvent without using an alkali, unlike a conventional extraction method or an active carbon absorption method. CONSTITUTION:A nonaqueous solvent containing phenol is brought into contact with an acrylic weakly basic ion exchange resin to make phenol adsorbed and the ion exchange resin containing adsorbed phenol is treated with a phenol- soluble nonaqueous solvent to elute the phenol. As the ion exchange resin, an ion exchange resin obtained by introducing one or two or more kinds of primary amines, secondary amines and tertiary amines into an ion exchange resin using an acrylic-divinylbenzene copolymer as a substrate is used. As the phenol-soluble nonaqueous solvent, a solvent containing a polar solvent such as acetone, methanol, ethanol, propanol or acetonitrile, especially acetone is preferably used. An absorption amount >=2 times larger than the ion exchange capacity of the ion exchange resin is obtained by using the acrylic weakly basic ion exchange resin.
