(31) The indium sesquioxide with over 99% purity can be prepared by a decomposition of nitric acid. The method was characterized by fewer equipments, simple operation, low cost and quick yield.

(32) Its main synthesis method is nitration of guaiacol by fuming nitric acid and glacial acetic acid as nitration agent.

(33) Specimens prepared by polishing and etching in a weak solution of nitric acid and alcohol reveal the lamellar structure of alternating plates that forms on slow cooling.

(34) The test results show that the reaction process of decomposition of witherite with nitric acid is the typical mass-transfer control process, in which the hydrogen ion diffuses through liquid film.

(35) In the medium of nitric acid, the trace chloride in the cement concrete was determined by turbidimetry.

(36) The controlling methods of nitric acid tail gas is evaluated, and the ways to reduce the quantity of nitric oxide emission in nitric acid process is explored.

(37) According to the trait of rocket propellant a kind of protective gloves made of composite fluorine rubber is developed which can be used to protect the skin of red fuming nitric acid worker.

(38) Most of traditional polishing process formulas for stainless steel contain chromic acid, hydrofluoric acid,[http://sentencedict.com/nitric acid.html] nitric acid and other strongly poisonous chemicals.

(39) Silver azide does not dissolve in water or in nitric acid.

(40) Methods Firstly make waste nitric acid into urea nitrate by chemical synthesis, and then produce industrial explosive power by cool mixing.

(41) And nitric acid salt, nitrite is united in wedlock possibly in human body stomach with amine, form inferior saltpetre amine, this is very powerful carcinogen.

(42) Treatment of the body after psychro-thermal cycles through in vitro experiments with nitric acid silver staining ammoniation, enhancement.

(43) Dissolve a pinch of silver and mercury in a solution of nitric acid, drop in a lump of metal amalgam, and soon a spidery, glittering "Tree of Diana" will form on the glass.

(44) Dissolving sample with nitric acid and hydrofluoric acid, the silicon content of silicon-manganese alloy was made a measurement with ICP-AES method in the hydrofluoric acid-resistant spray devices.

(45) The corn flour is hydrolyzed into glucose by sufouric acid. And after that the glucose, under the catalysis of metavanadate and sufouric acid, is oxidized into oxalic acid by nitric acid.

(46) The experiments have shown that the technology of oxidation degradation with nitric acid and sulfoxidation with sodium sulphite to produce water-reducer of cement with decomposed coal is available.

(47) The indium sesquioxide with over 99% purity can be prepared by a decomposition of nitric acid.

(48) A process of recovery of the nitric acid and nitro compounds from mononitrotoluene (MNT) waste acid by toluene extraction was introduced.

(49) The dependence of the extraction distribution ratios on the concentrations of aqueous nitric acid, extractant, salting-out agent and the temperature was investigated.

(50) And effects of raw materials size, reaction temperature, reaction time and nitric acid dosage on the output and lead chromate content of the product were discussed in detail in this paper.

(51) Black stripes after dip in nitric acid Conversion coating is dull.

(52) Phenols and anilides can be nitrated with very dilute nitric acid.

(53) The macro-kinetics characteristics of decomposition of witherite with nitric acid in a batch reactor are studied.

(54) The carbon fiber-reinforced Polylactide (C/PLA) was prepared for bone fracture fixation, and the carbon fiber was treated by surface soakage with concentrated nitric acid.

(55) Corrosion resistance experiment: salt water spray experiment, experiment, sulphur dioxide experiment, nitric acid hydrogen sulphide experiment, etc.

(56) The ore sample was dissolved in nitric acid. After enrichment and separation with Xanthic ester cotton, the silver was determined by thiocyanometry.

(57) The SERS spectra of a series of cyanine dyes in silver sol and ad- sorbed on silver or copper film etched by nitric acid are reported and compared.

(58) Nitric acid: Inorganic compound, colourless, fuming, highly corrosive liquid, chemical formula HNO 3.

(59) The decalcifying time could be shortened obviously by microwave at low temperature and nitric acid.

(60) Methods The forced swimming was used to set chronic stress model. Using nitric acid deoxidize enzyme method, the NO levels of serum and hippocampus were measured.
