Common knowledge of  K+   Ion

 
What is the use of potassium ions in water? Why is it called a "health barometer" for water quality? ​
 
Potassium ions (K ⁺) are naturally occurring "electrolyte members" in water. Just like potassium ions in human blood are necessary to maintain heartbeat, the concentration of potassium ions in water can also reflect the water quality status. The concentration of potassium ions in natural water bodies generally ranges from 1 to 10mg/L. If there is a sudden surge, it may be due to industrial wastewater (such as drainage from fertilizer plants and electroplating plants) being secretly discharged into the water, or pesticides from farmland being washed into rivers with rainwater. At this time, it is important to be alert to water pollution.
 
 
What are the requirements for measuring potassium ions in water? Why can't we just look at one number? ​
Potassium ion concentration is a "multifaceted mirror" for judging water quality, but when measuring it, one must understand the "tricks":
Industrial wastewater: Potassium ions>50mg/L may be mixed with potassium fertilizer or potassium containing cleaning agents, and the discharge outlet should be checked; ​
Surface water: Sudden increase may be due to the inflow of potassium fertilizer from farmland with rainwater, and it is necessary to consider indicators such as ammonia nitrogen and phosphorus to determine whether it is eutrophic; ​
Seawater: Potassium ions are already high (about 380mg/L), but abnormal fluctuations may indicate red tide or marine pollution. ​
Moreover, water temperature and pH value can interfere with the measurement, so sensors with temperature compensation (such as LoRaWAN potassium ion sensors) need to be used for real-time data calibration.
 
 
How many potassium ions in the water are considered excessive? Is there a safety standard? ​
Different scenes have different 'red lines':
Drinking water: The World Health Organization (WHO) recommends that potassium ions should be less than 10mg/L (too high can cause bitterness). Although China's "Drinking Water Standards" do not impose a mandatory limit, caution should be taken when exceeding 20mg/L to prevent water source pollution; ​
Fishery water: Potassium ions>50mg/L can affect the osmotic pressure of fish, leading to gill damage. Aquaculture is usually controlled at 10-30mg/L; ​
Industrial circulating water: Potassium ions>100mg/L are prone to scaling, and reverse osmosis membranes are commonly used in power plants to "reduce potassium" and ensure that equipment is not blocked.
 
 
What kind of artifact are used to measure potassium ions now? How to achieve both speed and accuracy? ​
Nowadays, the popular "wireless intelligent detective" - LoRaWAN potassium ion sensor, is like an underwater "chemical tongue":
Probe will taste: Use an ion selective electrode (ISE) to "lick" water and measure potassium ion concentration within 10 seconds; ​
Anti interference expert: The built-in chip can filter out the "disturbance" of calcium and magnesium ions, even if there are many impurities in the water, it will not affect it; ​
Wireless carrier pigeon: No need to pull wires, data can be transmitted several kilometers away with LoRaWAN protocol, and water quality changes can be monitored on mobile phones at any time, which is 10 times faster than traditional manual sampling!
