摘要:
An indium adsorbent is provided that is obtained by the following process. A hydrophilic polymer having a carboxyl group in which indium is incorporated in advance is caused to absorb an aqueous solution of a water-soluble monomer, a cross-linking agent, and a polymerization initiator, and an acid treatment is performed on a polymer obtained by polymerizing the water-soluble monomer, to obtain the indium adsorbent. The indium adsorbent has a template architecture with respect to indium. Accordingly, the indium adsorbent is capable of adsorbing indium with a high selectivity. An indium selection rate is 2.0 or more with respect to zinc.

The present invention relates to an aqueous electrolyte solution absorber including an aqueous electrolyte solution absorbent polymer obtained by introducing a hydrophilic polar group to a water insoluble polymer and a material to be sucked. The aqueous electrolyte solution absorber is produced by filling a water permeable bag type member with the aqueous electrolyte solution absorbent polymer obtained by introducing the hydrophilic polar group to the water insoluble polymer and a material to be sucked. The aqueous electrolyte solution absorber is inexpensive and has a high safety, a broad applicable range and a good handling property upon transportation or storage. Thus, a large amount of aqueous electrolyte solution absorbers can be rapidly conveyed at one time even to a risky place where persons are endangered to convey the absorbers.

The recycling apparatus of waste sulfuric acid for collecting waste sulfuric acid generated at a source site A, transporting it by a carrier B, and recycling it for reuse at a user site C, the recycling apparatus of waste sulfuric acid including a receiving tank for receiving virgin sulfuric acid (a) and waste sulfuric acid (b) having a concentration different from that of the virgin sulfuric acid, and including (1) a mixer alone, (2) a mixer and a concentration monitor, or a mixer and a cooler in combination, or (3) a mixer, a concentration monitor, and a cooler in combination.
摘要:
According to the present invention, a water absorbent material and materials to be sucked included in a water permeable bag type member form a water absorber. Thus, the water absorber is small both in weight and volume upon its transportation, and accordingly, the water absorber can be rapidly conveyed in large quantities without depending on a human power. The water absorber absorbs water upon its use to adequately satisfy a function of a form traceability for weight, volume and outline.
摘要:
An antimicrobial agent utilizes a resin having acrylonitrile and styrene and/or a conjugated diene as units. The antimicrobial agent includes a metal-salt-containing copolymer, and the metal-salt-containing copolymer is obtained by treating a copolymer containing acrylonitrile and at least one of styrene and a conjugated diene as units with an acid to thereby introduce acid radicals into the copolymer, and converting at least part of the acid radicals into a salt of at least one metal selected from among Ag, Cu, and Zn.

摘要:
A recovered disc of a structure in which plural disc substrates are bonded together with an adhesive, is to be recycled. To this end, there is provided a recycling method for a recovered disc wherein a recovered disc, containing a material of at least one coating film, out of a reflective film, a recording film, a protective film and an ink film, deposited on a disc substrate in addition to an adhesive used for bonding a plurality of the disc substrates together, is used as a starting material for preparing a flame retardant resin composition or resin molded product.
