compare several phage trichloroisocyanuric acid (TCCA) disinfectant resistance

Objective: To compare several phage trichloroisocyanuric acid (TCCA) disinfectant resistance. Methods: Suspension quantitative test methods, F2 phage, T4 phage, T7 phage inactivation test, and with the type Ⅰ poliovirus vaccine strains for parallel comparison.
A RED swordfish (Xiphophorus helleri) acute toxicity test to measure the trichloroisocyanuric acid (TCCA) lethal concentration and concentration on security swordfish results: 24,48,72 and 96h of lethal concentration (mg · L ^ -1) were 4.62,4.13,4.01,4.01, safe concentration of 0.40mg · L ^ -1. At the same time, the drug was measured in guinea pigs Aeromonas (Aeromonas caviae), Aeromonas hydrophila Aeromonas hydrophila subspecies (Aeromonas hydrophila hydrophila), Pseudomonas fluorescens (Pseudomonas fluorescens) and Lu Acinetobacter (Acinetobacter the minimum inhibitory concentration lwoffi) 4 inoculum were 0.156,0.078,0.078,0.078ug · mL ^ -1.
When the novel composition in compressed form is added to a water body such as a swimming pool, spa, or hot tub, a reaction between the trichloroisocyanuric acid (TCCA) and the alkali metal bicarbonate takes place which is believed to be expressed by the following equation in which sodium bicarbonate is the alkali metal bicarbonate:
Cl3 C3 N3 O3 +NaHCO3 →NaCl2 C3 N3 O3 +CO2 +HOCl (1)
That is, sodium dichloroisocyanurate is produced in situ. The reaction takes place rapidly and the sodium dichloroisocyanurate and hypochlorous acid formed readily release their available chlorine contents. The novel compositions consisting of trichloroisocyanuric acid (TCCA) and anhydrous alkali metal bicarbonate having a mole ratio of alkali metal bicarbonate to TCCA of from about 3:1 to about 1:1 have available chlorine concentrations in the range of about 45 percent to about 67 percent.
