Problems solved by technology

[0006] (1) After the chlorine-containing disinfectant is dissolved or diluted, the available chlorine is unstable in the aqueous solution, especially under the conditions of neutral and acidic medium, the half-life is generally only tens of hours, which affects the disinfection effect, such as the disinfection of drinking water, Add 2mg / L of available chlorine, and the concentration of available chlorine will not reach 0.05mg / L after 2 days, that is, the antibacterial time is generally less than 2 days;
[0007] (2) Hypochlorous acid decomposes in water to release Cl 2 , Cl 2 Not only pollute the environment, but also cause tearing, coughing, irritation of the skin and mucous membranes, and in severe cases, poisoning, suffocation and death
However, the currently developed chlorine stabilization technologies are all under alkaline conditions, and the pH value of the disinfectant is above 12-13
As mentioned earlier, under alkaline conditions, chlorine-containing disinfectants have low disinfection ability and poor application effect

Embodiment 1

[0025] Embodiment 1: take by weighing sulfamic acid 50g, sodium dichloroisocyanurate 8g (containing available chlorine 63%) and be dissolved in 1 liter of pure water, treat that it fully dissolves and place for 2 hours, add ammoniacal liquor 25ml again to colorless and tasteless ( Ammonia 25%), the synthetic chlorine-containing disinfectant available chlorine is 0.5%, pH is 2.32, and ORP value is 976mV. Stored for 90 days under the condition of being closed and not protected from light, the available chlorine is 0.47%, the pH is 2.28, and the ORP value is 978mV. The disinfectant is dissolved in pure water and diluted to an available chlorine concentration of 200mg / L, which can kill 99.999% of Escherichia coli and Staphylococcus aureus within 10 minutes; 99.999% kill Bacillus subtilis within minutes.

Embodiment 2

[0026] Embodiment 2: Weigh 20g of taurine, 8g of sodium dichloroisocyanurate (containing 63% of available chlorine) and dissolve it in 1 liter of pure water, wait for it to fully dissolve and place it for 2 hours, until it is colorless and tasteless, then add 10ml of ammonia water (Ammonia 25%), the synthetic chlorine-containing disinfectant available chlorine is 0.5%, pH is 2.42, and the ORP value is 972mV. Stored for 90 days under the condition of being closed and not protected from light, the available chlorine is 0.39%, the pH is 2.42, and the ORP value is 968mV. The disinfectant is dissolved in pure water and diluted to an available chlorine concentration of 200mg / L, which can kill 99.999% of Escherichia coli and Staphylococcus aureus within 10 minutes; 99.999% kill Bacillus subtilis within minutes.

Embodiment 3

[0027] Embodiment 3: take by weighing sulfamic acid 20g, sodium dichloroisocyanurate 8g (containing available chlorine 63%) and be dissolved in 1 liter of pure water, treat that it fully dissolves and place for 2 hours, add ammoniacal liquor 10ml again to colorless and tasteless ( Ammonia 25%), the synthetic chlorine-containing disinfectant available chlorine is 0.5%, pH is 2.42, and ORP value is 976mV. Stored for 90 days under the condition of being closed and not protected from light, the available chlorine is 0.45%, the pH is 2.41, and the ORP value is 978mV. The disinfectant is dissolved in pure water and diluted to an available chlorine concentration of 200mg / L, which can kill 99.999% of Escherichia coli and Staphylococcus aureus within 10 minutes; 99.999% kill Bacillus subtilis within minutes.

Abstract

The invention relates to a method for preparing chlorine-containing disinfectant with high electric potential. The method comprises the steps of: mixing complexing agent with chlorine-containing disinfectant according to a proper ratio (wt. ratio of available chlorine in chlorine-containing disinfectant to complexing agent is 1:2-1:10), and adjusting pH with ammonia water to 2-3 to obtain the final product with available chlorine 0.01%-0.5% and oxidation reduction potential (ORP) 900-1000mV. The complexing agent is sulfamic acid, and aminoethylsulfonic acid. Chlorine-containing disinfectant contains sodium hypochlorite, trichloroisocyanuric acid, and sodium dichloroisocyanurate. Available chlorine in the chlorine-containing disinfectant has the advantages of long keeping time, high stability, good disinfection effect, and low pollution.

Description

technical field [0001] The invention relates to the technical field of environmental protection and medical sanitation disinfection, in particular to a preparation method of a stable high-potential chlorine-containing disinfectant. Background technique [0002] Chlorine-containing disinfectants are the most widely used disinfectants, including various types, such as sodium hypochlorite, chloramine-T, trichloroisocyanuric acid, sodium dichloroisocyanurate, etc. Due to the advantages of low cost and high efficiency, chlorine-containing disinfectants are widely used in drinking water disinfection, environmental disinfection, medical and sanitation disinfection and other fields, and are currently the most widely used disinfectants in the world. [0003] There are two main dosage forms of chlorine-containing disinfectants: solid dosage form and liquid dosage form. The solid dosage form has the most types, and the liquid dosage form is less, mainly containing sodium hypochlorite,...
