Study the Possibility of Using Alginate Extracted from some Marine Algae in Reducing Calcium and Magnesium Concentrations from Aqueous Solutions
Abstract
In this research, the possibility of using alginates extracted from some marine algae was studied in reducing the concentrations of calcium and magnesium in the water. The alginates were extracted from three types of marine algae, namely Sargassum vulgare, Facus and Ulvalactuca. Samples were collected from the southern Corniche beach and Sports City in Lattakia, according to the yield of each algae for comparison, Facus algae was characterized by a high yield of alginates (34%) while S.vulgare (28%) while Ulva did not give any alginate yield. He studied the use of alginates extracted from brown algae to study the possibility of Reducing calcium and magnesium concentrations in the water, as standard solutions of calcium were prepared at concentrations of ppm (0,1,5,20,50,100,200) with a natural water sample whose hardness was determined by calibrating the formation of complexes of 180ppm. Sodium extracted from brown algae, compared with the removal rate of pure standardized sodium alginate, and then applied to a natural water sample.
