Abstract
A hybrid nanocomposite namely ๐ถโ๐โ/๐ท๐ธ๐ โ 51(๐๐ฆ) was developed toreduce the ๐๐ณ(๐๐) from a textile industry wastewater.๐ถโ๐โ/๐ท๐ธ๐ โ 51(๐๐ฆ) exhibited a good cristalinity. The photocatalyticreaction of the carboxyl groups of the composite is in center and it isassociated with the C-H-vibration. The optimal doping content of๐ถโ๐โ/๐ท๐ธ๐ โ 51(๐๐ฆ) was determined to be 1.2 mg/L to treat 1.6 mg/L๐๐ณ(๐๐) with a maximum yield of 98% at a sun light power of 80 mW/m2after 15 min at 42 ยฐ๐ถ in summer. After 5th times sun light experiments,the ๐ถโ๐โ/๐ท๐ธ๐ โ 51(๐๐ฆ) was reused with a yield of 97%. The ๐๐ณ(๐๐)reduction was explained with the Langmuir-Hinshelwood (L-H) kineticmodel.
