| Description
| - Voltametricky byl studován přenos K+ podporovaný dibenzo-18-crown-6 na rozhraní mezi vodou obsahující La3+, Eu3+ nebo Yb3+ a 1,2-dichloroethanem (DCE) obsahujícím distearoyl L-?-fosfatidylcholin (DSPC). Reverzibilní vlna pro přenos K+ z vody do DCE zmizela v důsledku tvorby kompaktní vrstvy na povrchu způsobené tvorbou komplexu lanthanového iontu s DSPC monovrstvou. Blokovací efekt vzrůstal v pořadí La3+<Eu3+< Yb3+. Konstanty tvorby komplexu byly stanoveny na základě poklesu voltametrického proudu. Potlačení reverzibilní vlny bylo provázeno vznikem nového voltametrického píku u kladnějších potenciálů pro obnovení přenosu K+ , což odpovídá rozrušení kompaktní vrstvy. Potenciál píku nové vlny se posouval ke kladným hodnotám se vzrůstem pH a koncentrace lanthanidového iontu. Byl rovněž prostudován blokovací efekt na přenos iontů tetraethylamonia, bis(tributylamonium)propanu, ClO4- nebo 1,5-naftalendisulfonátu. (cs)
- The transfer of K+ facilitated by dibenzo-18-crown-6 was examined voltammetrically at an interface between water containing La3+, Eu3+ or Yb3+ and 1,2-dichloroethane, DCE, containing distearoyl L- alpha -phosphatidylcholine, DSPC. The reversible wave for the transfer of K+ from water to DCE vanished owing to the formation of a compact layer at the interface, which was caused by the complex formation of lanthanide ion with DSPC monolayer. The blocking effect was enhanced in the order of La3+ < Eu3+ < Yb3+. The complex formation constants were approximately evaluated based on the decrease of voltammetric current. The inhibition of reversible wave was accompanied by the appearance of a new voltammetric peak at more positive potentials for the restoration of K+ transfer corresponding to the destruction of the compact layer. The peak potential of the new wave shifts positively with an increase of pH and the concentration of lanthanide ion.
