Finally,the most reasonable technological process of“stagewise grinding,coarse and fine classification,gravity separation magnetic separation reverse anionic flotation”has been found out.
Cast nylon modified with laurolactam was prepared by activated anionic copolymerization under the adiabatic condition.Its mechanical properties were studied.
Furthermore, the crystal structure, surface characters of quartz and clinochlore, and the solution chemistry of oleic acid as the anionic collector were analyzed.
Polynionic celluloses were preparated by alkalify and etherify of refining cotton.The degree of replacement of the polynionic cellulosesis was high.The radicals of replacement were distributed evenly.
A process for decolourization of anionic dye containing wastewater by using waste plastics in the presence of cationic auxiliary and sodium dodecylbenzene sulfonate has been studied.
Anion in inhalable particulate matter can be completely dissolved in water by using ultrasonator and then measured by ion chromatography.Good accuracy and precision can be obtained.
It has been proved that it is economical and feasible to eliminate educt alkali from coarse sodium tungstate with electrodialysis method of negative ion (1) selective membrane.
Results indicate interestingly that the double bond of GMA polymerized with polystyryl carbanion and the molar ratio of epoxy end group and polystyrene oligomer can be adjusted.
But they're really just positively-charged cations — like calcium, sodium, and potassium — and negatively-charged anions, like phosphate, sulfate, and bicarbonate.
And just last year, researchers in Australia managed to create the strongest superbase ever discovered — a compound called ortho-diethynylbenzene dianion.
