活性炭细化及在微波照射快速降解酸性红B中应用

Refinement of Activated Carbon and Application in Rapid Degradation of Acid Red B under Microwave Irradiation

在粉末状活性炭存在下,微波照射能快速降解酸性红B。对总体积25 mL,浓度100 mg/L的酸性红B溶液,活性炭加入量1.6 g/L,微波照射1.5 min时,降解率可达73.20%。同样条件下适当提高活性炭加入量,如3.2 g/L时,降解率可达到98.63%。因此,选择活性炭作为催化剂具有降解率高,速度快,成本低,降解彻底,无二次污染等优点,适合于大规模治理各种染料废水。

Acid red B can rapidly be degraded under microwave irradiation in the presence of activated carbon powder.The degradation ratio can reach 73.20% for 25mL total volume with 100mg/L initial concentration of acid red B and 1.6g/L addition amount of activated carbon under 1.5min microwave irradiation.Under the same conditions,the degradation ratio of acid red B is up to 98.63% by appropriate increasing addition amount of activated carbon of 3.2g/L.The technology of microwave irradiation integrated with activated carbon powder as catalyst is advantageous over high degradation ratio and rate,low cost,complete degradation,no intermediate products and no secondary pollution,which is fit for massive treating various kinds of dyestuff wastewater.
