The product, Factory Supply 1,3 - Propylenediaminetertaacetic acid/PDTA with CAS number 1939 - 36 - 2, is a high - quality chemical compound. PDTA is an organic acid chelating agent. It exists as a white or off - white powder under normal conditions. Its molecular formula is (C_{11}H_{18}N_{2}O_{8}), and the molecular weight is approximately 306.27 g/mol.
This product is known for its excellent chelating properties. It can effectively bind to metal ions such as calcium, magnesium, iron, and copper, forming stable complexes. The product is offered at a competitive price, making it an attractive option for various industrial applications.
2.1 Water Treatment: In water treatment processes, PDTA can be used to remove metal ions from water. It helps to prevent the precipitation of metal salts, which can cause scaling in pipes and equipment. By chelating metal ions, it improves the quality of water and reduces the corrosion of pipes and machinery.
2.2 Detergent Industry: PDTA is used in detergents to enhance their cleaning performance. It can chelate metal ions in hard water, preventing the formation of insoluble soap scum. This allows detergents to work more effectively, resulting in better cleaning results and less residue on clothes and dishes.
2.3 Pulp and Paper Industry: In this industry, PDTA is used to remove metal ions from pulp. Metal ions can cause discoloration and degradation of the pulp. By using PDTA, the quality of the paper product can be improved, and the brightness and strength of the paper can be enhanced.
When using PDTA, it is important to follow proper safety procedures. Wear appropriate protective equipment, such as gloves and goggles. The product should be stored in a cool, dry place away from heat and direct sunlight.
For water treatment, the dosage of PDTA depends on the concentration of metal ions in the water. Usually, a small - scale test is required to determine the optimal dosage. In the detergent industry, PDTA can be added during the manufacturing process. The amount added is typically based on the formulation of the detergent and the hardness of the water it is designed for. In the pulp and paper industry, PDTA is usually added at a specific stage of the pulp - making process to ensure effective removal of metal ions.
4.1 Water Treatment Case: A municipal water treatment plant was facing problems with high levels of iron and manganese in the water supply. The presence of these metal ions was causing discoloration of the water and corrosion of the pipes. After adding PDTA at a dosage of 5 mg/L, the iron and manganese levels were significantly reduced. The water quality improved, and the corrosion rate of the pipes decreased by 30% over a six - month period.
4.2 Detergent Case: A detergent manufacturer was struggling with the performance of its laundry detergent in hard - water areas. After incorporating PDTA into the detergent formula at a concentration of 2%, the cleaning power of the detergent increased significantly. Consumers reported that their clothes were cleaner and had less residue after washing, leading to an increase in sales by 15% in the hard - water market segment.
4.3 Pulp and Paper Case: A paper mill was experiencing problems with the brightness and strength of its paper products due to the presence of metal ions in the pulp. By adding PDTA at a dosage of 3 kg per ton of pulp, the metal ions were effectively removed. The brightness of the paper increased by 5%, and the tensile strength of the paper increased by 10%, resulting in a higher - quality paper product that was more marketable.
