| description | Lanthanum silicates nanoparticles with La9.33Si6O26 formula provided through sonochemical procedure in the presence of tetraethylenepentamine. The amine of tetraethylenepentamine plays two roles of alkaline agent and masking agent for controlling the morphology and size in the reaction process. Effect of sonication time and applying sonication method (non-stop or pulsed) as important parameters studied on the product characteristics. The obtained ideal sample applied as photocatalyst material for degradation of series of organic dyes. Also, dye concentration, catalyst dosage and pH are operational parameters in water treatment that choose to study in the designed photocatalytic tests. The photocatalytic degradation mechanism inquired to study the scavengers for active agents. Therefore, ideal efficiency (61.70%) obtained in the presence of 0.03 g La9.33 Si6 O26 nano-photocatalysts in 10 ppm acid red 14 in the pH of 11 which proceeds in terms of mechanism with the help of superoxide species. |
