Abstract
This paper presents a test method for determining the total hardness in natural and drinking waters using an indicator solution for test titration. The developed method offers a rapid and efficient procedure for assessing the total hardness across a wide range of water bodies. The relative standard deviation of a single result in determining the overall hardness does not exceed 10%. The lower limit for determining the total hardness is 1°dH/5 cm3 of the sample solution.
期刊介绍：
Journal of Water Chemistry and Technology focuses on water and wastewater treatment, water pollution monitoring, water purification, and similar topics. The journal publishes original scientific theoretical and experimental articles in the following sections: new developments in the science of water; theoretical principles of water treatment and technology; physical chemistry of water treatment processes; analytical water chemistry; analysis of natural and waste waters; water treatment technology and demineralization of water; biological methods of water treatment; and also solicited critical reviews summarizing the latest findings. The journal welcomes manuscripts from all countries in the English or Ukrainian language. All manuscripts are peer-reviewed.
