Preliminary Studies of Methylene Blue Remotion from Aqueous Solutions by Ocimum basilicum

The continuous expansion in the textile industry results high loads of coloured wastewaters that heavily pollute limited freshwater sources. Therefore, a wide array treatment methods has been used to remediate water/wastewater from dyes. One common practice is use plants degrade, absorb, metabolise, and detoxify different types pollutants, including This study employs sweet basil (Ocimum basilicum) as phytoremediation model herb remove concentrations (5–25 mg/L) methylene blue (MB) dye synthetic water, taking into account effects MB concentration contact time (up 10 days). showed ability Ocimum basilicum absorb decreased with increase increased time. best removal was 93% when 25 mg/L days. Additionally, it noticed relative growth rate (RGR) herbs adversely influenced by increasing RGR value 2.2 g/day 5 mg/L.
