What is the primary use of your Potassium Sulfite in the photography industry?
In photography, it serves as an essential protective agent in developer solutions. It preferentially reacts with oxygen, preventing the oxidation and degradation of the developing agents, which ensures consistent image quality and extends the solution's shelf life.
Why is your Potassium Sulfite suitable for high-purity applications like photography and electronics?
Because it is produced and tested to meet the stringent GB/T 22409-2008 / ISO 5990:2000 standard for photographic-grade chemicals. This standard mandates low levels of impurities, ensuring it will not interfere with sensitive processes like film development or PCB manufacturing.
Can we use your Potassium Sulfite for dechlorination in our RO water treatment system?
Absolutely. It is an effective and safe dechlorinating agent for RO systems. It quickly neutralizes residual chlorine, protecting the delicate RO membranes from oxidative damage, which is crucial for maintaining system efficiency and longevity.
