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;

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,...
