生物炭改性g-C₃N₄光催化剂的制备及耦合芬顿反应原位降解甲基橙

Preparation of g-C₃N₄ Photocatalyst Modified by Biochar and In-Situ Degradation of Methyl Orange by Coupled Fenton Reaction

针对芬顿反应中二价铁离子和过氧化氢利用率低,生成的铁泥无法分离等问题,设计利用松塔,氢氧化钠,三聚氰胺为原料,采用高比表面的生物炭为载体,通过热缩聚法来制备生物炭g-C3N4复合光催化剂原位降解甲基橙的性能研究,探讨染料工业废水治理更有效的技术途径。

In view of the low utilization rate of ferric ion and hydrogen peroxide in Fenton reaction, the resulting iron mud can not be separated and other problems, the design uses pine tower, sodium hydroxide and melamine as raw materials, and uses biochar with high specific surface as the carrier to prepare biochar g-C3N4 composite photocatalyst for in situ degradation of methyl orange by thermal polypolymerization. To explore the more effective technical approach to the treatment of dye industry wastewater.
