In Eq. (13), at time 0, the concentration of CIP and phenol are represented by [CIP]0 and
[Phenol]0, respectively;whileafter absorbeddose“D”ofgammairradiation, thecorresponding
concentrationofCIPandphenolarerepresentedby[CIP]Dand[Phenol]D, respectively.
When a straight line is plotted by taking ln CIP½ �D

2.2.Computationof●OH,eaq �and●Hwithnorfloxacin
Norfloxacin (NORO)maybecalled likewise chemotherapeutic antibacterial agent, furthermore
is regularlyutilized tomedicine forurinary tract infections [23]. Its occurrence in surfacewater
andwastewater overflows has been accounted for at follow ppb levels [12, 14, 24–27]. Even
though, thedetectedconcentrationofNOROisverylowandnormallyranges fromngL�1 toμg
L�1 inwaterbodies andμgkg�1 tomgkg�1 in soils andsediments, still these fluoroquinolone
family are categorized as “pseudopersistant” contaminants because of their continuous and

ThepresenceofNOROin the freshwaterbodies indicate that traditionalwastewaterorwater
treatment techniques are not efficient to removeNORO fromaquatic environment due to its
aromatic nature and its occurrence cause thoughtful health associated problems by using
contaminated drinking water [31–33]. Therefore, it becomes an issue of interest to remove
NOROfromtheaquatic environment.

The following Eq. (14) was employed to measure the bimolecular rate constant of •OH,
eaq � and •H, which are the main species produced during gamma radiolysis of aqueous
media [21]. Competition Kinetics: An Experimental Approach
