Results showing the stability of the solutions used in the method. (a) The stability of stock solution prepared and kept under refrigeration. The results show that the solution was stable for about 23 days, after which the absorbances recorded were significantly different from the initially recorded values. (b) The stability of the 100% concentration calibration solution prepared during the samples analyses. The result showed that the prepared solution was stable for 9 days, beyond which it may not be advisable to use such solution.
