Number Of Binding Sites

Molecularly imprinted polymers of bisphenol A were synthesized with a sol-gel process on the supporter of silica nanospheres. The BPA-imprinted silica nanospheres were characterized by scanning electron microscope, dynamic adsorption, static adsorption tests and molecular selectivity tests. Scatchard analysis revealed that two classes of binding sites were formed in the imprinted polymers, the equilibrium association constant and the apparent maximum number of binding sites were estimated to be 0.20 μmol•ml-1 and 137.55 μmol•g-1, respectively. Bisphenol A and three analogues, tetrabromobisphenol A (TBBPA), bisphenol C (BPC) and nonylphenol (NP) were employed for selectivity tests. The results indicated that the imprinted polymers exhibited excellent selectivity and specificity toward bisphenol A.

ABSTRACTPhysical properties and structural parameters have been measured for ropes of nylon 6 as a function of the number of use operations. The fractional content of the α crystal form, sound velocity, birefringence, tensile strength and length all increase systematically and significantly with increasing the number of use operations. The fractional content of the γ crystal form and fiber diameter decrease with use. These trends indicate that the measurement of such properties and structural parameters, especially the length, provide a possible basis for establishing a reliable, rapid, and convenient nondestructive characterization method to predict the remaining service life of nylon 6 ropes.
