Sodium nitrate NaNO 3 is a salt and a solid Not the same thing You can use sodium nitrate with sulfuric acid and make nitric acid If you use a distilling rig you can make pure nitric acid Without distilling the acid you would get some sulfuric acid in the mix and it can make silver refining
The aim of this study was to examine nitrate removal by quaternized silica gel q SG in ternary solutions of nitrate phosphate and sulfate under flow through column conditions q SG was synthesized by grafting dimethyloctyl[3 trimethoxysilyl propyl] ammonium chloride on silica gel [21] reactive orange 12 removal by gold nanoparticle

A total of 108 silica capsule experiments were performed in order to determine the solubility of gold in aqueous solutions containing both NaCl and H 2 S at temperatures of 250 300 and 350°C at pressures dictated by vapor/liquid coexistence The starting materials in the capsules were H 2 O S° goldwire NaCl 0 to 4m ± Na 2 SO pH a H 2 S aq aH 2
The replacement of sodium citrate with C 16 TAB in the seed formation step Since the reduction of silver nitrate on the gold nanorod surface by ascorbic acid in aqueous surfactant media a silane coupling agent is used as a surface modifier to enhance the affinity of gold for silica which is then deposited from aqueous
The solubility of amorphous silica was obtained in aqueous sodium nitrate solutions up to six molal and at temperatures from 25 to 300°C It was expected that solubilities in aqueous sodium chloride solutions would be similar At 25°C the solubility of amorphous silica is lowered from that in water to m in m sodium nitrate or a
