A method of testing the composition or quality of water includes dissolving about two parts by weight of a 2-hydroxybenzyl alcohol and about one part by weight of a sodium nitroprusside in about seventy-five parts by weight of a polyethylene glycol; adding the sodium nitroprusside solution to a water sample to catalyze an indophenol monochloramine reaction; and detecting the concentration of monochloramine in the water sample. The polyethylene glycol may be a polyethylene glycol 300, a PEG-400 or a PEG-1000. The method may also be accomplished with a solution made by dissolving a 2-hydroxybenzyl alcohol and a sodium nitroprusside in a mixture of propane-1,2-diol and water.

The present invention provides a polyamide composite, including the following components: 20 to 80 parts of a polyamide resin; 1 to 30 parts of a red phosphorus flame retardant; 0.01 to 10 parts of trimethallyl isocyanurate; and the polyamide composite has a cross-linked structure between polyamide molecules. By adding trimethallyl isocyanurate (TMAIC) for irradiation cross-linking treatment, and by the red phosphorus flame retardant, not only the polyamide composite can meet the needs of flame retardant, but also glow-wire ignition temperature (GWIT) and comparative tracking index (CTI) have been improved.
