糠醛渣对废水中Cr3+的吸附研究OACHSSCDCSTPCD
Absorption of Cr3+ from Wastewater by Furfural Residue
研究了糠醛渣对Cr3+的吸附性能.通过低温N2吸附-脱附等温线和红外光谱对糠醛渣的结构进行了表征；室温下,考察了吸附时间、溶液pH、Cr3+的初始质量浓度和糠醛渣的粒径对糠醛渣吸附Cr3+的影响.结果表明,糠醛渣为介孔吸附材料并且表面含氧官能团很丰富；当1 000 μm的糠醛渣加入量为1.0g,吸附时间为25 min,溶液pH=4,Cr3+的初始质量浓度ρ0=4.9 mg/L时,溶液中Cr3+的去除率为84.2％,且随ρ0的增加而增大.糠醛渣良好…查看全部>>
Isoliquiritigenin and its derivatives ( 3a ~ 3j ) are synthesized in ethanol from 2, 4-dihydroxyacetophenone and substituted benzaldehyde under microwave with KOH as catalyst with yields of 65% to 89%. Their structures are characterized by 1H-NMR, IR, MS spectra, The factors such as temperature, material ratio, the amount of solvent, the microwave irradiation power and time will affect the yield of Isoliquiritigenin and its derivatives.
