The experimental results have shown that ofloxacin in HCl (0. 1 mol/L)solution has maximum absorptivity at 293nm. Good linear correlation is seen between concentrations of ofloxacin in the range of 18 μg/ml and their absorptlvity. The results of experiment of stability show that light and heat have almost no effect on ofloxacin otic Solution. The validity is two ...
