*Actual concentration measured by AA of each filtrates are very close to each other except the number 2(gluteraldhyde filtrate of 30 min). (we stop the measurement too early therefore actual concentration of this filtrate should be ignored)
 
*AA results supports the UV-vis results from 14/11/1012.
