Thermal gravimetric and differentiated

Thermal gravimetric and differential thermal analyses of dried sanqjles were performed on a DuPont 990 Thermal Analyser. X-ray diffiaction patterns were obtained on a Siemens D500 diffiactometer coupled to a Cu x-ray tube. A nickel filter selected the Ka radiation. Surface areas were obtained by nitrogen physisorption at 75K using a Micromeritics Accusorb 2100E apparatus. CCI4 adsorption was performed on a TGA-7 Perkin Elmer Thermal analyser, for...
