WebbThe pH-jump reagent can induce the acidic degradation of ZIF-8 using UV light to realize the controlled release of Pro. Thus, the physical properties of PD@ZIF-8, such as its release, formulation stability, and adhesion, were investigated in detail. WebbThe reagent flow should essentially be proportional to the difference between the hydrogen ion concentration of the process fluid and the setpoint. A reagent control valve must therefore have a rangeability greater than 10,000,000:1 for a setpoint of 7 pH when the incoming stream fluctuates between 0 and 7 pH. tsn 1200 ottawa
