Trace metal species in 1 L of sample can be coprecipitated with indium hydroxide at pH 9–9.5 by using 1 mL of indium nitrate solution (100 mg/mL) and 0.3 mol/L sodium hydroxide solution. After adding 2 mL of sodium oleate solution (1 mg/mL in 70% ethanol) and 1 mL of SDS solut...
In addition, practical developers usually contain (1) an alkali (commonly a hydroxide or carbonate of sodium or potassium, or sodium metaborate or tetraborate) to adjust and maintain the hydrogen ion concentration (acidity or pH) to a value appropriate for sufficient development activity; (2) an...
