Table 1.

Weight loss of the clay AP and of the modified AP with a mixture of the surfactant A-P.

Samples TH2O (°C) H2O (%) Tmax (°C) Surfactant Loss (%) Incorporated Surfactant (%) Residue to 260 °C (%)
AP 71 10.25 - - - -
APOA:P 49 1.31 275–302 18.50 68.39 3.71
APO3A:P 53 2.00 292 15.40 61.09 4.02
APO9A:P 58 2.59 282 16.34 70.12 4.34

TH2O—volatilization temperature of the water; H2O—percentage of water loss; Tmax—maximum decomposition temperature of the surfactant.
