How to make CDS

CDS preparation is a chemical process that has attracted increasing interest in recent years due to its applications in various fields, from water disinfection to health support. However, its use and preparation require in-depth and accurate understanding to ensure safety and effectiveness.

In this post you will learn how to make CDS at home safely and effectively . We will explain not only the specific steps involved in the preparation, but also the necessary precautions, ethical considerations, and responsible uses of this chemical. Preparing for this chemical adventure is essential to the use of CDS , and we invite you to explore every detail with us.

Elements necessary for the preparation of CDS

Preparing CDS (Chlorine Dioxide) at home requires specific ingredients that are essential to ensure the safety and effectiveness of the process. Before we dive into the preparation process, it is essential that you fully understand what ingredients you need and their importance in making this solution. Below, we break down in detail the ingredients needed for the preparation of CDS .

1. Sodium chlorite (NaClO2)

Sodium chlorite is the main ingredient in the preparation of CDS. This chemical agent can have a concentration of 25%, 24.5%, 22.5% or 28%. Its main characteristic is that it acts as an oxidant and does so quickly and stably, which is why it is very easy to use. On the other hand, it has antibacterial properties that make it perfect for eliminating viruses, microorganisms and bacteria.

2. 4% hydrochloric acid (HCL) or 50% citric acid

Hydrochloric acid or citric acid are used to activate sodium chlorite and release chlorine dioxide. These acids play a critical role in the chemical reaction that converts sodium chlorite to CDS. The choice between citric acid and hydrochloric acid depends on your preferences and availability, but both are effective.

3. Distilled or mineral water (500 ml)

The water used in the preparation of CDS must be of the highest quality. Distilled water is preferred to avoid any possible contamination or impurities that may interfere with the chemical reaction. However, you can also use mineral water. On the other hand, the steam generated by the reaction between sodium chlorite and hydrochloric acid will be stored there.

4. 500 ml container

In this container the preparation of the CDS will be carried out and within it the chemical reaction will take place. It is recommended that it have a lid and that it closes tightly. In addition, it is convenient that it be made of glass including its lid. It is also important that the container has the necessary space to place a glass of at least 10 ml inside and that it can close perfectly.

5. Syringe

The syringe will facilitate the process of extracting the liquids of both chemical compounds and then placing them in the container. Furthermore, it is easier to measure the appropriate amount of compound to be used for the preparation of the CDS. On the other hand, it is recommended that a syringe with a catheter tip be used, since its design makes the entire transfer process to another container simpler, as it has better precision and control.

6. Glass of at least 10 ml

This glass will be placed inside the 500 ml container, since the ingredients for the preparation of the CDS will be mixed in it. Take into account that it is necessary for this container to be high so that the distilled water does not exceed it and mix with the Sodium Chlorite and the activator while the chemical reaction occurs. Likewise, it is also essential that the packaging allows the container to be closed correctly so that it remains inside.

How to prepare CDS at home

Preparation of CDS is a process that must be carried out precisely by following proper measures. Below, we will guide you through the steps necessary to prepare CDS at home safely and effectively. Take into account that for this we will take a measurement of 500 ml of water for every 5 ml of product. Once you have all the necessary materials and ingredients, you must follow the following process:

Step 1: Preparation of the container

The first thing is to place the 500ml container on the surface we will work on and open its lid. Then you must insert the glass into this container, placing it in the center. Now fill the container with 500 ml of distilled water or until it does not exceed the edge of the container that was placed inside.

Step 2: Mixing Sodium Chlorite and Acid

To prepare the CDS, you will need to carefully measure the ingredients. Taking into account the measurement or relationship we are using, add 5 ml of Sodium Chlorite first and then 5 ml of Hydrochloric Acid. To do this, use the syringe, which you must fill up to 5 ml and then place it in the glass inside the container. Then repeat the process with the Hydrochloric Acid, adding it slowly and carefully, as chlorine dioxide can be released in the process.

Step 3: Generation of chlorine dioxide

After mixing Sodium Chlorite and Hydrochloric Acid, the chemical reaction will begin to generate chlorine dioxide gas, so you will see how it changes color. This is why you should immediately close the container with its lid. This ensures that chlorine dioxide is concentrated within it and prevents it from escaping into the environment. Next, move the container to a dark space, such as a closed closet, for at least 12 hours. During this time, chlorine dioxide gas will be generated and mixed with distilled water.

Step 4: Repeat the process

After 12 hours, you can remove the container from where you have stored it. You will be able to see that the distilled water has taken on a light yellow color, as it has mixed with chlorine dioxide. However, it still does not have a concentration of 3,000 ppm, but 1,500 ppm. Because of this , the process or chemical reaction must be repeated .

To do this you must open the container, remove the packaging inside and close the container again. During these steps it is recommended that you put on a mask or do it in a ventilated area. On the other hand, you can store the liquid inside the glass separately to use for cleaning.

Now add 5 ml of Sodium Chlorite and 5 ml of Hydrochloric Acid to the container again. Immediately open the container and carefully place the container inside it. Close the container again and take it back to the closet where it remains in a dark place for 12 hours while the chemical reaction occurs. After that you will have prepared CDS at 3,000 ppm and ready to use it.
