Effect of ultrasonic on removal of total sulfur by co-solvent of hydrogen peroxide: acetic acid (PAA) solution / Adhwa Nadia Nor Saidi
The fossilized plant material known as coal, which ranges in colour from dark brown to black and resembles graphite, has historically played a significant role in energy production. However, sulfur is one of the main pollutants present in coal, which contributes to air pollution. This study addresse...
