A method of forming an alkali metal-doped calcium-SiAlON material is provided. The method includes mixing calcium-SiAlON powder and an alkali metal hydroxide to form a reaction mixture. The mixture further includes spark plasma sintering (SPS) the reaction mixture at 800 to 940 degrees Celsius (&#xb0; C.) to form the alkali metal-doped calcium-SiAlON material. The alkali metal hydroxide is present in an amount of 0.1 to 10 weight percentage (wt. %), based on a total weight of the reaction mixture.

The method for detection of cyanide in water is a method for the detection of a highly toxic pollutant, cyanide, in water using ZnOnanoparticles synthesized locally by an elegant Pulsed Laser Ablation technique. ZnOnanoparticles having a median size of 4 nm are synthesized from pure zinc metal target under UV laser irradiation in a 1-10% HOenvironment in deionized water. The synthesized ZnOnanoparticles are suspended in dimethyl formamide in the presence of Nafion, and then ultrasonicated to create a homogenous suspension, which is used to prepare a thin film of ZnOnanoparticles on a metal electrode. The electrode is used for cyanide detection.
