At the points where the 1st and 2nd lines intersect, and where the 2nd and 3rd lines intersect, draw perpendiculars to the x-axis to estimate the milliequivalents of sodium hydroxide taken up by the sample at those points. The point where the 1st and 2nd lines intersect will give the ...
The effect of sludge disintegration on molecular weight distribution of dissolved organic carbon (DOC) is demonstrated by size exclusion chromatography with online organic carbon detection (SEC-OCD). Ozone, ultrasound and sodium hydroxide were used to disintegrate excess sludge. Significant differences on...
We are manufacturer of different kinds of pseudo boehmite, activated alumina for adsorbent, desiccant, catalyst and catalyst carrier, zeolite molecular sieves and high whiteness aluminum hydroxide.Our company has an excellent technical R & D team, which can provide clients with special product R ...
Regeneration of the amine solvent is achieved by stripping the zinc with sodium hydroxide, sodium hypochlorite, or alkaline or acidic formaldehyde solutions. Because they readily extract free cyanide as well as anionic metal cyano complexes, the high-molecular-weight quaternary amines show considerable ...
0.4 g of 25% aqueous sodium hydroxide solution are also added, and the materials are mixed at 131° C. for 30 min on a rotary evaporator. The mixture is then filtered by way of a pressure filter funnel with a Seitz K 100 filter layer. This gives a clear, colorless, viscous solution,...
