Potassium and calcium content in padelegan water which is used as the raw water for making salt

Abstract

Potassium and calcium are elements contained in seawater. The presence of potassium and calcium in raw saltwater were impurities in producing non-food salt. On the other hand, potassium and calcium as target minerals are desirable in mineral-rich healthy salt (food salt) production. Information about the potassium and calcium content in raw salt water can assist in analyzing the quality of the salt to be produced. The purposes of this study were; to determine the content of potassium, and calcium in Padelegan waters used as a source of salt raw materials, compare them with other locations, and their correlation with water quality. The potassium and calcium content in the sample were determine used the AAS (Atomic Absorption Spectrophotometry) method. Potassium concentrations ranged from 221,870 to 285,110 mg/L, and those for calcium from 497,700 to 552,713 mg/L. The potassium content in Padelegan waters is smallest than other reference waters. In contrast, the calcium content in Padelegan waters is greatest than in other reference waters.
