AI Article Synopsis
- A new natural polymer flocculant (PBCF) made from bagasse cellulose was created to enhance the removal of humic acid from water.
- PBCF showed effective flocculation at a dosage of 60 mg/L and a pH between 6.0 and 9.0, achieving over 90% removal efficiency for humic acid and chemical oxygen demand in synthetic water.
- In real lake water tests, PBCF successfully reduced turbidity by 91.6% and dissolved organic matter by 50%, highlighting its potential as a safe and eco-friendly water treatment solution.
Article Abstract
A newly green natural polymer bagasse cellulose based flocculant (PBCF) was synthesized utilizing a grafting copolymerization method for effectively enhancing humic acid (HA) removal from natural water. This work aims to investigate flocculation behavior of PBCF in synthetic water containing HA, and the effects of flocculant dose and initial solution pH on flocculation performance. Results showed that PBCF functioned well at a flocculant dose of 60 mg/L and pH ranging from 6.0 to 9.0. The organic removal efficiency in synthetic water in terms of HA (UV) and chemical oxygen demand (COD ) were up to 90.6% and 91.3%, respectively. Furthermore, the charge neutralization and adsorption bridging played important roles in HA removal. When applied for lake water, PBCF removed 91.6% turbidity and 50.0% dissolved organic matter, respectively. In short, PBCF demonstrates great potential in water treatment in a safe and environmentally friendly or 'green' way.
