POTASSIUM TETRAPHENYLBORON METHOD CODE 3639-SC QUANTITY CONTENTS CODE 30 mL *Sodium Hydroxide, 1.0N *4004WT-G 5 g *Tetraphenylboron Powder *6364-C 1 Spoon, 0.05 g, plastic 0696 *WARNING: Reagents marked with an * are considered hazardous substances. To view or print a Material Safety Data Sheet (MSDS) for these reagents see MSDS CD or our web site. To obtain a printed copy, contact us by e-mail, phone or fax. Potassium, as the seventh most common element on the Earth, may be found in minor quantities in most water supplies. It seldom exceeds 10 ppm in drinking water and usually is less than 2 ppm. In some brine or runoff in agricultural areas the potassium concentration may reach 100 ppm. APPLICATION: Drinking, surface, and saline water. RANGE: 0.0–10.0 ppm Potassium METHOD: Potassium reacts with sodium tetraphenylborate to form a colloidal white precipitate in quantities proportional to the SAMPLE HANDLING & PRESERVATION: potassium concentration. Store samples in polyethylene bottles, not in soft glass where leaching of potassium from the glass may occur. Samples may be acidified to pH 2 with nitric acid, but should be neutralized before analyzing. INTERFERENCE: Calcium and magnesium interfere at very high concentrations. Check for stray light interference (see p. 17). Smart2 TEST PROCEDURES 2.04 Potassium 1/2
