Thermal behavior measurement
Thermogravimetric analysis
were conducted by a METTLER TOLEDO TGA/DSC 1 thermogravimetric
balance. About 8 mg of pretreated RWSS and control were
placed, respectively, in a ceramic sample holder and heated at
10 C/min under an argon atmosphere (50 mL/min) in the temperature
range of 35–600 C.
