Thermogravimetric study of polyacrylamide with evolved gas

Dried samples of polyacrylamide in an He atmosphere have been subjected to thermogravimetric analysis in the 30–600°C range, and the evolved gases were monitored by FTIR. Water, ammonia, and small quantities of carbon dioxide are released in the first stages of decomposition (220–340°C), where the polymer chains remain intact and the

In this study, thermogravimetric analyser-gas chromatography-mass spectrometer (TGA-GC-MS), a simple and fast technique, is used to estimate the composition of the microalgae. About 20.0 mg algae sample (0.2 mm) was placed on a ceramic crucible and heated at minimum heating rate required for the setup (20 °C/min) under inert atmosphere to 900 °C.

Thermogravimetric analysis (TGA) was used in this work to study the decomposition of polymers and their individual constituents. The derivative of the TGA curve with respect to temperature, is known as the derivative thermal gravimetric (DTG) thermogram, which can clearly identify differences in decomposition rates of screened polymers.
