Water quality--Determination of TNT--Sodium sulfite spectrophotometry
Determination of sulfite in dehydrated garlic using high performance liquid chromatography with post-column derivatization
Therefore, it is feasible to substitute conventional alkaline deinking by near-neutral sulfite deinking in paper plant.
The results show that the mixture of corncob xylan and sulfite pulp as carbon resource could stimulate the synthesis of xylanase and cellulase;
If you do hold wine for over six months, you may wish to add a bit of sulfite to prevent discoloration, unless, of course, someone in the house has asthma.
Unbleached sulfite pulp
A method for synthesizing sodium sulfoacetic is discussed, which sodium sulfoacetic is synthesized with sodium sulfite and ethyl monochloro acetate, with sodium sulfite and chloroacetic acid.
Spectrophotometric determination of micro sulfite in waste water with chloroauric acid
The effects of bleaching additives on hypochlorite single-stage high temperature fast bleaching of reed neutral sulfite pulp is studied in this paper.
"The oxides are sulfur dioxide and sulfur trioxide, which when dissolved in water make sulfurous acid and sulfuric acid, respectively. Several sulfur compounds with halogen elements are industrially important. Sodium sulfite (Na2SO3) is a reducing agent used to pulp paper and in photography."
acid sulfite pulp
The study of xylanase treatment on mechanism of acidic hydrogen peroxide bleaching of sulfite pulp
Minor cationic polymer clay stabilizer PTA was synthesized with epichlorohydrin and dimethylamine as monomers and potassium persulfate - sodium sulfite as initiating agent.
sulfite oxidase deficiency
Research on the technology of getting sodium sulfite from the by-product of AC fomaing agents;
The process is carried out by using Soxhlet set, as experiment unit, with methyl sulfonic acid as a catalyst and magnesium sulfite as dehydrating agent, giving 97.
The effect of cooking additives on potassium sulfite straw cooking
Because of their larger size and structure, gypsum crystals settle and dewater better than calcium sulfite crystals, reducing the required size of by-product handling equipment.
Sodium sulfite (Na2SO3) is a reducing agent used to pulp paper and in photography.
sulfite liquid trap
The optimum condition of the separation enrichment by column chromatography with activated charcoal and sodium sulfite strip and extraction of trace gold with TMK-isoamyl alcohol has been studied.
Bleached sulfite pulp
Development of non-toxic gold electrolytes, such as those based on sulfite complexes rapidly increased in recent years.
The application of spent sulfite cooking liquor( red liquor) and the isolated lignin to foundry industry was developed.
