Near infrared spectroscopic characterisation of surface hydroxyl groups on hydrothermally treated silica gel
(Journal article; Peer reviewed, 2011)Surface hydroxyl groups on hydrothermally treated silica gel have been under discussion several decades back with contradictory conclusions. Some authors meant that the hydrothermally treated sila gel increases the ... -
Pyrolytic formation of polyaromatic hydrocarbons from steroid hormones
(Journal article; Peer reviewed, 2011)Four steroid hormones, namely androsterone, cholesterol, estrone and estradiol, have been pyrolysed at 300, 400 and 500 °C and the pyrolysates from these have been analysed by GC-MS. The results indicate that these formed ... -
The use of anthracene as a model compound in a comparative study of hydrous pyrolysis methods for industrial waste remediation
(Journal article; Peer reviewed, 2011)Polycyclic aromatic hydrocarbons are very stable compounds and tend to bioaccumulate in the environment due to their high degree of conjugation and aromaticity. Hydrous pyrolysis is explored as a technique for the treatment ...
