Description
| - An effective, rapid and simple analytical method for the determination of Na, K, Ca, Mg, Al, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, V and Zn at mg.kg-1 levels in pure and ultra-pure NaOH, KOH, NaCl and KCl using the optical emission spectrometry was developed. The method was shown to be very sensitive with limits of detection: Na 0.902, K 2.96, Ca 0.0636, Mg 0.0257, Al 0.427, B 0.127, Ba 0.0153, Cd 0.0232, Co 0.0562, Cr 0.0412, Cu 0.0632, Fe 0.0600, Li 0.0169, Mn 0.0347, Mo 0.189, Ni 0.0549, Pb 0.389, Sr 0.0299, V 0.0651 and Zn 0.0428 (all in mg kg-1).
