摘要:
The present invention discloses a method for solidifying and stabilizing waste acid including steps of condensing waste acid containing phosphoric acid to reduce the volume; mixing the condensed waste acid with waste acid containing fluoroboric acid to solidify and stabilize the mixed waste acid. The pH of the mixed acid is adjusted by adding barium hydroxide as a neutralizer. The efficiency of solidifying waste acid can be improved by partially granulating and by adding solidifying agent indirectly. The method of the present invention can prevent intensely exothermic reaction caused by adding solidifying agents. Furthermore, the method of the present invention is controlled in a temperature of 30 to 45° C. to improve the polymerization of the mixed waste acid so that the efficiency of solidification thereof can be also improved.

A technique of fabricating a medium-high temperature CO2 sorbent of layered nano-carbonate is provided. A CO2 sorbent is fabricated. The sorbent captures CO2 at a medium-high temperature above 600° C. Calcium acetate is introduced for making a nano-scale layered double hydroxide (LDH). The layered structure is used for templated synthesis. The sorbent has an initial conversion rate above 90%; and the conversion rate remains the same even after 100 times of carbonation/de-carbonation cycles.

The present disclosure uses a nano-SiO2 powder as a supporter with H2PtCl6 added as an electro-catalyst precursor. A chemical reduction is processed at a high temperature to adhere nano-sized Pt ions on the nano-SiO2 powder through reduction. Thus, a nano-Pt catalyst using nano-SiO2 as supporter is manufactured for fuel cells, organic compound reactions and the textile industry.

Disclosed is a device for separating radioisotope thallium-201. The device includes an evaporation unit for a solution vial, a first glass vial connected to a first valve and a second valve, an ion exchange column connected to a third valve, a second glass vial connected to a fourth valve and a fifth valve, a collection vial for receiving solution from the fifth valve, a product vial with a membrane filter and a vacuum unit connected to the first valve, the fourth valve and a sixth valve. This device can separate out high-concentration thallium-201 solution from which radioisotope thallium-201 can be obtained.
摘要:
The present invention relates to an air filtering system capable of enhancing inspection convenience, which is disposed in the ceiling and comprises a housing, a filter, a first sampling tube, and a second sampling tube. On both ends of the housing, an intake and an outtake are disposed opposite to each other. The filter is disposed in the housing, and has an intake surface and an outtake surface opposite to each other. The filter divides the inner space of the housing into a first sampling zone and a second sampling zone. A first end of the first sampling tube is fixed on the housing, and communicates with the first sampling zone. Likewise, a first end of the second sampling tube is fixed on the housing, and communicates with the second sampling zone. Besides, a second end of the first sampling tube and a second end of the second sampling tube are both fixed on the wall. Thereby, the inspection convenience for the inspection staffs can be enhanced.
摘要:
A restraining apparatus for restraining a squeezed CRD blade includes two clips, two connective plates and a nut. The clips are made with a U-shaped cross-sectional configuration. The connective plates are used to connect the clips to each other so that the connective plate and the clips together form an annular structure for restraining the CRD blade. The nut is provided between the connective plate and can be engaged with a threaded section of an operative rod so that the operative rod is operable to move the restraining apparatus.
