Liquid-liquid extraction properties of new calixarene derivatives D to Pb~(2+) & Cd~(2+) were studied,and the comparison of the properties with the self-made calixarene A and its derivatives B,C were made.
The analysis results showed that the optimal conditions are capacitance 25 #F, electric resistance 200#, voltage 2.5 kV, D600 0.3-0.4, cuvette with an interelectrode distance of 0.2 cm, concentration of plasmid 0.1 #g/ml, cell concentration 2.5#1012, aminobenzylpenieillinare concentration 50 #g/ml.
Syntheses and metal ions recognition of dendritic calix[n]arenes (n = 6,8) amide derivative
Liquid crystalline behavior and fluorescent property of calixarene containing azobenzene photochromic group
It was found that the calixarene skeleton was a good platform for conformation immobilization of azobenzene photochromic group and the formation of liquid crystalline.
Solubility, Acid-Base and Complexation Properties of Calixresorcinarene in Aqueous Solutions of Nonionic Surfactants
Solubility and acid-base properties of calixresorcinarene (H8L) in aqueous solutions of nonionic surfactants Triton X-100, Triton X-405, and Brij-35, as well as isopropanol were studied by pH-potentiometry.
Also measured are the rate of gas heating and the distributions of gas and electron density and of translational temperature in the cross section of the discharge cuvette in plasma of dc glow discharge and contracted discharge.
The radial dependence of the distribution of energy release in plasma of contracted discharge is suggested, and a solution is found of heat equation, which describes the distribution of translational temperature over the cuvette radius.
Increasing the sensitivity of fluorescent analysis by coating a preparation on a plate diagonally cutting the cuvette
It is shown that there is a threshold for the excitation of a vortex rotating much more rapidly than the cuvette.
A graphite micro-cuvette is employed for chlorine-specific analyses using indium chloride emission bands at 359.9 nm.
