The invention relates to a method for synthesizing magnesium-aluminum composite oxides with different densities, wherein a hydrogen peroxide-containing magnesium nitrate and aluminum nitrate mixed salt solution is added to an ammonia water solution to prepare the magnesium-aluminum composite oxides with different densities. According to the present invention, the prepared carrier is the magnesium-aluminum composite oxide, the pore volume, the pore size and the density of the magnesium-aluminum composite oxide can be changed by adjusting the hydrogen peroxide feeding amount, the pore volume range is 0.3-1.0 ml/g, the pore size range is 10-30 nm, and the bulk density range is 0.3-1.0 g/ml; and the synthesized composite oxide can be adopted as the carrier of the catalyst of the dehydrogenation reaction for alkane (isobutane and C100-C130 n-alkanes) preparation, and the prepared catalyst has high catalytic dehydrogenation activity and high stability.

A catalyst for catalytic wet oxidation treatment of isothiazolinone waste water, preparation and an application thereof belong to the field of water treatment technology and environment functional materials. Isothiazolinone is a broad-spectrum high-efficient, low-toxin, and inoxidizable biocide, and is widely used in industries of oil field, papermaking, pesticide, cutting oil, leather, printing ink, dye, leather making, and the like. However, isothiazolinone waste water generated during isothiazolinone production is not biochemically degradable. The invention discloses a catalyst for catalytic wet oxidation, which has corrosion resistance, high temperature resistance, high strength, and large specific surface area; according to the preparation method, modified zirconia is adopted as a carrier, precious metals such as Ru, Pt, Pd, Rh and Ir that have high activity and are not easy to run off are carried, and an excellent catalyst for catalytic wet oxidation is prepared. The prepared catalyst ...

Method for determining chloride ions in chrome ore

Номер: CN0102183574A

The invention discloses a method for determining chloride ions in a chrome ore, which belongs to the technical field of determining the content of chloride ions in the chrome ore. In the method, a chrome ore sample is dissolved by a sulfur-phosphor mixed acid, so that a solution to be determined is prevented from generating Cr6+; loss of the chloride ions is prevented by dissolving the chrome ore sample with a capped closed container; influence of coexistence elements on the determination result of the chrome ore solution to be determined is reduced by adding a total ionic strength adjustment buffer (TISAB), and the content of the chloride ions can be accurately determined by an ion selective electrode method.
