Abstract :
Spectropholornetrie technique is used to evaluate binding of the vanadium(1U) ion to a water solublecaruc[4] arene molecule in aqueous solution. On the basis of the calculated value formation constant at25rC.we found that the eomplexation of this metal on is very favored towards 25, 26, 27, 2Stetrahydroxy-5, 11, 17, 23-tetnmulphonalic acid-calix[0]areneGaussian 03 package.
