Heavy metal pollution, particularly from copper ions, is a growing environmental concern due to factors like population growth and industrialization.
A study was conducted to create a new adsorbent from pumpkin husk modified with KOH to effectively remove copper ions from water.
The results showed that KOH-modified pumpkin husk had a significantly higher sorption capacity for copper compared to raw pumpkin husk, with various factors influencing its effectiveness including pH and temperature.
