Low-cost, local production of a safe and effective disinfectant for resource-constrained communities

Improved hygiene depends on the accessibility and availability of effective disinfectant solutions. These disinfectant solutions are unavailable to many communities worldwide due to resource limitations, among other constraints. Safe and effective chlorine-based disinfectants can be produced via simple electrolysis of salt water, providing a low-cost and reliable option for on-site, local production of disinfectant solutions to improve sanitation and hygiene. This study reports on a system (herein called “Electro-Clean”) that can produce concentrated solutions of hypochlorous acid (HOCl) using readily available, low-cost materials. With just table salt, water, graphite welding rods, and a DC power supply, the Electro-Clean system can safely produce HOCl solutions (~1.5 liters) of up to 0.1% free chlorine (i.e.,1000 ppm) in less than two hours at low potential (5 V DC) and modest current (~5 A). Rigorous testing of free chlorine production and durability of the Electro-Clean system compo..., We conducted chemical experiments in a laboratory setting, performing each experiment in triplicate unless otherwise specified. The dataset presented here includes the raw data from these experiments. We used Excel to record the data and calculate the average and standard deviation. The file names correspond to the figures or tables in the manuscript or the Supporting Information Appendices.

The files below contain the raw data for each figure and table present in the manuscript titled \"Low-cost, local production of a safe and effective disinfectant for resource-constrained communities\" and supporting information. Experimental methods and instruments used for data collection are described in the main manuscript.

## Description of the data and file structure

All files are in Excel. Below are the descriptions of each file: 

#### **Chlorine production by carbon electrodes in batch process.**

This file contains the raw data of batch experiments with a volume of 1.35 L. Three trials are reported here. The current, in amps, was recorded at various electrolysis times. Other measurements include the measured Free Chlorine concentration in parts per million (ppm), and pH after electrolysis.
