INVESTIGATION INTO THE PROPERTIES OF CLAY DOPED WITH SILVER ION FOR USE AS A CATALYST.

Abstract

The work on the investigation into the properties of clay doped with silver ion for use as a catalyst has been carried out. The clay sample from Ilorin from Ilorin, Kwara State, Nigeria was ground, sieved and calcined in a furnace at a temperature of 550- 600°C for a period of 6hrs. The sample was doped with silver ion using 0.2M of NaOH/NaCl Solution with 0.2M AgNO, in a ratio 2:1. The sample was than analyzed using X-ray fluorescence equipment (XRF) [Cement X-ray spectrometer, PW 1660, Philips X-ray Analyser) with a monitor. The following results were obtained 33.44% SIO 23.11% Al,O), 9.87% FejO), 3.86% CaO, 1.98% MgO, 0.01% SO. 0.87% K₂O, 0.71% NaO, 8.61% LO.I. 3.03% L.S.F. 1.01S/R and 2.34% A/R for the calcined sample. While that of the doped samples are 33.15% SO. 22.10 Al2O. 9.23% FeO.. 4.44% CaO, 1.99% MgO, 0.04% SO), 0.96% K,O, 8.10 L.O.1, 3.55 L.S.F. 1.06 S/R and 2.39 A/R. These results when compare with samples having catalytic properties was found to be suitable for use as a catalyst.
