Description
  • Nový macrocyklický ligand, 1,4,8,11-tetraazacyklotetradekan-1,8-bis(methylfosfonová kyselina) (Dipon) má vysokou termodynamickou a kinetickou selektivitu pro měďnaté ionty vzhledem k ostatním přechodným iontům kovů. Metoda počáteční rychlosti(lambda = 310 nm, pH = 3.75, C(L) = 4.6 x 10(-3) mol L-1) za optimálních experimentálních podmínek má nejvyšší citlivost stanovení. Dynamický koncentrační rozsah je(5-200) x 10(-6) mol L-1, a detekční limit je 2.5 x 10(-6) mol L-1. Metoda standardního přídavku byla použita pro kinetické stanovení Cu2+ k eliminaci efektu interferujících iontů (např. Zn2+, Ca2+, Mg2+, Cd2+, Pb2+, Mn2+, Co2+, Ni2+, HCO3-, Cl-, SO42-, etc.). The metoda byla testována na umělých a reálných vzorcích a poskytla odpovídající výsledky, které jsou ve shodě s výsledky analýz pro certifikované materiály. Výhodami navržené metody jsou rychlost, jednoduchost a robustnost. (cs)
  • A new macrocyclic ligand, 1,4,8,11-tetraazacyclotetradecane-1,8-bis(methylphosphonic acid) (refered to as dipon) exhibits high thermodynamic and kinetic selectivity for Cu2+ compared to other transition metal ions. The initial-rate method (lambda = 310 nm, pH = 3.75, C-L approximate to 4.6 x 10(-3) mol L-1) was chosen as an optimal experimental approach in order to achieve maximum sensitivity of determination. The dynamic range of the method is (5-200) x 10(-6) mol L-1, and the detection limit is 2.5 x 10(-6) mol L-1. A standard addition procedure was applied to the kinetic determination of Cu2+ to eliminate the effect of interfering ions (e.g. Zn2+, Ca2+, Mg2+, Cd2+, Pb2+, Mn2+, Co2+, Ni2+, HCO3-, Cl-, SO42-, etc.). The method was tested on artificial and real samples (alloys, pure and spiked mineral water) and gave satisfactory results which are in agreement with the values for some certified materials. The advantage of the proposed method is rapidity, simplicity and robustness in the presence of ot
