Language	Name	Abstract	Keywords
cze	Stanovení kovových nečistot v čistých hydroxidech a solích pomocí ICP OES	Byla vyvinuta efektivní, rychlá a jednoduchá analytická metoda pro stanovení Na, K, Ca, Mg, Al, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, V a Zn na koncentračních úrovních mg.kg-1 v ultračistých solích MgCl2 CaCl2 pomocí optické emisní spektrometrie. Metoda má následující detekční limity: 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 a Zn 0.0428 (vše v mg kg-1).

eng	Determination of metal impurities in pure hydroxides and salts by ICP OES	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).
