Aloke Kumar Ghoshal, Prabirkumar Saha, in Progress in Filtration and Separation, 2021. 9.3.1.4 Optimum Operation Conditions. LM-based separation is found to be an efficient way to extract bioactive compound like catechin. TBP–SFO–ethanol is found to be good carrier–solvent– stripping agent combination. The optimum conditions for the BLM studies are pH = 4.0, carrier concentration = 0
An improved stripping process for removing as produced aluminide coatings and exposed aluminide coatings from cobalt base and nickel base superalloys, using 1/2 to 5 percent of hydrofluoric acid or an acid fluoride having at least one mole of hydrofluoric acid, 3 to 20 percent of nitric acid and water, permissibly including a low foaming or nonfoaming wetting
The invention provides a stripping solution for the chemical nickel-plated coating of a cast aluminum piece. The stripping solution contains nitric acid, sodium 3-nitrobenzene sulfonate, nickel powder, pure water, hydrofluoric acid and sodium chloride. The stripping solution provided by the invention is capable of realizing secondary utilization of unaccepted materials generated in the
2) By incorporating chelating or complexing agents in the stripping solution that have a greater affinity for the metal being removed than for the base material. 3) By adding inhibitors to stripping processes to chemically or physically adsorb onto the substrate and “protect” it from the stripping
Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. A process of stripping the following coatings: aluminide, corroded aluminide, chromium-aluminum, aluminum-titanium, chromium-aluminum silicon, aluminum-iron and aluminum-iron-chromium from superalloys having a base of the class consisting of cobalt, nickel, and cobalt and nickel, which

Acidic stripping solutions comprising hydrogen peroxide as oxidant, either at least one phosphorous-oxy acid, or the addition of nitric acid, together with accelerators and surface active agents, are effective for the rapid and selective removal of protective hard surface coatings and nickel-base brazes from a variety of metal
different stripping agents of dispersion phase on Sm(III) separation. Experimental results indicate that the optimum separation conditions of Sm(III) were obtained as that HCl concentration was 4.00 mol/L, p204 concentration was 0.150 mol/L, and volume ratio of membrane solution and stripping solution (O/W) was 1.00 in the dispersion
Stripping of Pt from the loaded organic phase was attempted using HCl, NH 4 Cl, NH 4 SCN, NaSCN, aq NH 3 and aqueous mixed solution of NH 3-NH 4 Cl as stripping reagents at unit phase ratio . These reagents were found to be unsuitable for stripping of platinum from loaded organic phase due to poor stripping efficiency
