In contrast, the anion requires a strong base to restore.
The adsorption capacity of cationic exchange resin for various cations is different, and their strength and relative relation are as follows:
Ba2 + > Pb2 + > Sr2 + > Ca2 + > Ni2 + + > > Cd2 CU2 + + > > Co2 Zn2 + > magnesium 2 + > > Cs1 Ag1 + + + > > K1 NH41 + > > H1 Na1 + +
The bonding strength of anion exchange resin and anions is as follows:
S02-4 + > I - > NO3 - > NO2 - > Cl - > HCO3 - > OH - > F -
If the anion exchange resin is exhausted and there is no reduction, the fluorine with the weakest adsorption will gradually appear in dialysis water, resulting in soft bone disease, osteoporosis and other bone diseases.
If the cation exchange resin is consumed, the hydrogen ion will also appear in the dialysis water, resulting in an increase in the acidity of the water, so it is necessary to monitor the ion function effectively.
Generally is * the resistance coefficient of water quality (resistivity) or conductivity (conductivity).
The ion exchange resin used in the ionic method also causes bacterial reproduction to cause bacteremia, which is a noteworthy point.
