Phosphonates
Problems arising out of interference of the undesired metallic ions in the processes, the formation of scales and deposits in the equipment like heat exchangers etc. are frequently encountered in the industry. Phosphonates offers effective solutions to many of these problems with its array of diverse key properties. These products are available in acid form as well as in the form of sodium salts, with each molecule having distinct advantage for specific applications.Key Properties:
1.Sequestration:
The multivalent metal ions like Calcium, Magnesium, Copper, Zinc etc. can be complexed with Phosphonates at stoichometric levels, forming a stable water soluble complex that suppresses unwanted effects of metal ions in various processes.
2.Threshold effect:
The scalant mixture can be kept in a solution form by a low concentration of Phosphonates (below the stoichiometric levels), exhibiting a threshold effect.
3.Hydrolytic Stability:
Phosphonates are highly stable and resistant to hydrolysis over a wide range of pH and temperatures unlike polyphosphates.
4.Deflocculation (Dispersion):
Phosphonates gets adsorbed on the growth sites of scalants. This hinders the growth of crystals from getting cluttered.
5.Corrosion Control:
Phosphonates in combination with Zinc Phosphate, Molybdate or Nitrate, offers synergistically enhanced corrosion inhibition in water systems compared to any of the individual components.
6.Chlorine Stability:
In the industry, Chlorine is used as an oxidizing agent as well as a biocide. Phosphonates are stable in systems containing chlorine.
Applications:
Phosphonates are used for: Cooling water treatment, Boiler water treatment, Soaps and Detergents, Textile processing, Bottle washing, Industrial & Institutional cleaners, Deflocculation of slurries, Antiscalant formulations for oilfields, Sea water evaporators, Reverse Osmosis & Sugar processing.The sodium and calcium salts of EDTA (ethylenediaminetetraacetic acid) are common sequestrants in many kinds of foods and beverages. The EDTA molecule can bind to metal ions by forming six bonds to it - two from nitrogen atoms in amino groups and four from oxygen atoms in carboxyl groups.
