N2  - ABSTRACT
As mankind grows, so does the world of consumerism, urbanisation, and industry, and 
this boom demography allows for a significant increase in the amount of waste being 
released into the environment. There is a serious ecological issue for human health 
because a number of these wastes include heavy contaminants and non-biodegradable 
substances. All of these heavy pollutants need thorough and adequate waste treatment 
before they are discharged into the environment. Recent years have seen the textile 
sector play a significant role and utilise a lot of colours.
The volumes and quality of wastewaters from these industries are quite significant, 
necessitating an adequate treatment technique for their waste. In this investigation, 
ozone treatment will be used to break down AB113 (ozonation). For various studies, 
the dye was produced in a volumetric flask at a particular concentration and diluted 
with distilled water. When analysing a solution, the pH is adjusted by either adding 
HCl or NaOH. Without adjusting the pH, the entire assay is repeated thrice in order to 
stabilise the pH between 3 and 10.
Samples of the AB 113 solution were taken during the experiment at various intervals 
(0–90 minutes), and they were then instantly analysed using UV/VIS 
spectrophotometry. It was discovered that AB113 degrades at a good pace for a while 
without modification (0–90 min). There was another improved removal rate when the 
pH was adjusted to 10 at the same duration (0-90 min) because of structural stability 
and the presence of hydroxyl radicals, which possess a higher oxidation potential 
compared to molecular ozone. Ozone treatment removes AB113 at 80% efficiency.
