Abstract
PURPOSE:To measure the density of chlorine ion accurately irrelevant to the presence of melamine sulfonate, by adding boric acid to a ready-mixed concrete to perform a measurement with the density of hydrogen ion below 7.0. CONSTITUTION:A chlorine ion measuring electrode body 1 is made of a sensitive film 3 comprising a mixture of silver chloride and silver sulfide fixed at one end of a cylindrical support 2 and a silver line 4 connected to the back of the film 3. A comparison electrode body 5 is made up of a potassium chloride liquid 8 housed in a container 7 forming a liquid junction 6 at the tip thereof and an internal pole 9 comprising silver chloride immersed thereinto. When the electrode bodies 1 and 5 thus obtained are immersed into a top liquid of the ready-mixed concrete to measure the density of chlorine ion, boric acid is added beforehand to shift the density of hydrogen ion below 7.0. This enables accurate measurement of the density of chlorine ion with dissociation made impossible even in the presence of melamine sulfonate.
