The US ferric chloride market is generally in a balanced state of supply and demand, producers say, although the market is becoming "a little tight," the result of increasing demand and tightness of key raw materials. Substantial increases in raw material and distribution costs have also led major ...
Plants take up chloride as Cl- ion from soil solution. It plays some important roles in plants, including in photosynthesis, osmotic adjustment and suppression of plant disease. However, high concentrations of chloride can cause toxicity problems in crops and reduce the yield. The toxicity results from accumulation of chloride in the leaves.
BPS Ferric Chloride is a ready made solution, no need to add any catalyst, filtration etc. just fill it and use it concept .

Mar 02, 2009· Ferric chloride vs. ferrous chloride March 2, 2009. Q. We use ferric chloride in our wastewater plant. We treat mostly copper (copper sulphate) and just a small bit of chrome. I have read a lot of people use ferrous chloride. Is there much difference in the performance or use of these two chemicals when treating copper?
Ferric chloride, also called iron chloride, is a chemical compound with a chemical formula of FeCl3. It has a relatively low melting point, and its boiling temperature is around 315 degrees Celsius. When dissolved in water, ferric chloride undergoes hydrolysis and gives off heat in an exothermic reaction.
