Physicochemical Studies on the Surface Water of River Nile and Its Canals

Abstract

The study of surface water chemistry mainly based on the results of the chemical analysis which carried out for the thirty-nine (39) collected water samples. The analysis includes the determination of the different properties of water such as electric conductivity(EC), hydrogen ion concentration (pH), total dissolved salts (TDS), turbidity , major ions as cations ( Ca 2+ , Mg 2+

Range and Average of Hydrochemical Ratios of the Different Surface Water Samples in River Nile and Canals

“…Measurements of the constituents of surface water samples , (5,6) : Pipet a volume of sample into a porcelain dish and add one drop of phenolphthalein, if solution turns pink, titrate against sulphuric acid (0.01N) from a burretdropwise until the colour just disappears, and designate this burret reading as (y) and add 2 drops of methyl orange and titrates against sulphuric acid 0.01N to the just orange colour, designate the new burret reading as (z).  Calcium and magnesium constituents:…”

“…I-(Na+K)Cl,( Na+K) 2 Regarding the hypothetical salt combination in the River Nile, canals and mixed water, three main assemblage are detected: In River Nile and canals the assemblage (I) in (12) samples represent (32%), as in Table ( 6) and Fig (7). The presence of Na 2 SO 4 salt in this assemblage is true indication of dissolution of terrestrial salts from continental deposits.…”

“…In mixed water one main assemblage is detected: assemblage (III) present in all samples of water (6) samples represent (15%) (two chlorides, two sulphates and one carbonates) as in Table (6) and Fig (3). Because of the chloride is dominant these indicate that the origin of the water is sea.…”
