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.
