The pH of the solution affects the surface properties of the adsorbent as well as dissociation of the adsorbate molecule[[] Ahmed El Nemr, Ola Abdelwahab, Amany El-Sikaily, Azza Khaled: Journal of Hazardous Materials. 161 (2009), p. 102–110. ].The variations in the amount adsorbed of dye from solution at various solution pHs are shown in Fig.1.

For instance, the oxidation resistance of Ti3SiC2 was reported by Zhou et al.[6] and Tong et al.[7] to be excellent at temperatures below 1100°C due to the formation of a protective SiO2 surface layer.
However, oxidation of Ti3SiC2 was detected by Racault et al.[8] to commence as low as 400°C through the formation of an anatase-like TiO2 film that eventually transformed to rutile at 1050°C.

Šimor et al. [4], who have used a plasma discharge element manufactured of an alumina plate upon which TiN strips were deposited using the magnetron sputtering method while the induction electrode was made of Molybdenum.
It also agrees with the results of Jozef Ráhel et al. [6] who have used a plasma reactor made of an alumina dielectric plate along with tungsten electrodes.
