Purpose: The Chao Phraya River is the main river in the central region. It is essential for consumption, agriculture, industry, and ecosystem conservation. In addition, in the area along the Chao Phraya River, there is agriculture, and industry is a source of conservation for many ecosystems. The support of brine from the sea has influenced the sea. The research aims to find the optimum conditions for applying the eelectro-adsorption technique to reduce salinity of the brackish water that can be used in agriculture. Graphite-type electrodes that are easily available and do not require surface treatment are used. Design/methodology/approach: The research aims to reduce the salinity value of brackish water salinity by DC to DC converter electro-sorption of the sample (790 μS.cm-1) with graphite electrode measuring the reduced electrical conductivity. The variables of salinity reduction, electric potential, temperature, and solution stirring have been studied. Removing ions from electrodes involves ultrasonic vibration and temperature. The important reason that graphite electrodes are used in electrosorption is that graphite is a good conductor. The structure of graphite is such that it has many electrons floating freely between the different layers. Findings: The research found that graphite electrodes could absorb electricity by controlling the electric potential (Charging) at 2.0 V for 25 min and at a temperature of 500C without stirring the solution while absorbing ions. It can reduce the salinity to 777 μS.cm-1, representing 1.64%. The optimum condition for washing electrodes used for 15 min at 2.0 V electrode potential for regeneration was washing electrodes without applying electrode potential (Discharge) in high-temperature water and with ultrasonic vibration. It can effectively wash off ions from the surface of graphite electrodes. Research limitations/implications: The ion adsorption of graphite electrodes was only electrical adsorption. Originality/value: The graphite materials have electrosorption properties at low potential and can be readily renewed by discharging the potential. They do not require surface treatment.
