Description
Technical field
The invention belongs to power grid construction field, particularly a kind of device measuring ion exchange resin exchange capacity.
Technical background
Ion exchange resin is widely used in generating plant, pharmaceutical factory, electron trade, plays an important role purifying water, except in anions and canons, removing organism etc. in anhydrating.Exchange capacity is the important performance indexes of ion exchange resin, and it is related to naval stores quality and the water yield processed, is related to the price between supplier and user and interests, so Accurate Determining ion exchange resin exchange capacity important in inhibiting.
Ion exchange resin CEC refers to that Board Lot (weight or volume) resin can carry out the total amount of the chemical group of ion-exchange reactions, and the temperature of reaction of ion exchange resin and soak solution, equilibration time are the key factors affecting exchange capacity.For in standard GB/T/T8144-2008 " Zeo-karb exchange capacity assay method " " mensuration of Hydrogen weak-acid cation-exchange resin CEC ", it is to the effect that got a certain amount of resin after treatment and proceeds in tool plug triangular flask, add 100mL standard solution of sodium hydroxide and cover tightly bottle stopper, put and soak 3 hours to 60 DEG C of water-soluble pots, be cooled to room temperature, soak solution 25mL in tool plug triangular flask (must not sucking-off resin) is shifted out with transfer pipet, put into another Erlenmeyer flask, add appropriate reagent water and indicator, titration is carried out with hydrochloric acid standard solution, volumescope according to consuming normal hydrochloric acid liquid calculates Hydrogen weak-acid cation-exchange resin CEC.
Defect and the deficiency of this method of GB/T8144-2008 and operation existence 4 aspects is proved through test of many times:
A.GB/T8144-2008 method regulation " soak solution is put and soaked 3 hours to 60 DEG C of water-soluble pots, is cooled to room temperature " weak point: soak solution takes out and is cooled to room temperature from 60 DEG C of water-soluble pots, and in cooling procedure, required cool time depends on ambient temperature.But room temperature is variable element, in same region, room temperature is different throughout the year; Even if different geographical on the same day, room temperature is also different, and thus soak solution is also different because of the change of room temperature parameter from 60 DEG C of times being cooled to room temperature, and namely resin equilibration time in soak solution, with season, geographical diversity and changing, is underrange.So soak solution is during being cooled to room temperature, weak-acid cation-exchange resin and the adsorption equilibrium that the sodium hydroxide solution in soak solution is set up create ion exchange resin exchange capacity error at measurment because equilibration time is different.
B. soak solution is cooled to its type of cooling of room temperature is that variable element (1) cools naturally; (2) water quench is used.The type of cooling is different, and the time that soak solution is cooled to room temperature is different, produces ion exchange resin exchange capacity error at measurment.
C. this operating conditions of soak solution 25mL in tool plug triangular flask (must not sucking-off resin) is shifted out with transfer pipet harsh, should not grasp, especially when resin wet true density is less, at the top of soak solution, middle part, bottom resin all adrift, resin will be inhaled into transfer pipet accidentally, cause test titration error, produce ion exchange resin exchange capacity error at measurment.
D. in water-bath, in order to prevent bottle stopper tripping, the weight that need add 500g heavy is pushed down, and this regulation is difficult.Due to taper stopper band point, with weight push down band point object because of contact point too little, weight is pressed on bottle stopper insecure.Because bottle internal gas pressure is high in test, bottle stopper is backed down and is slipped to the accident broken into pieces on the ground and happens occasionally, cause test to stop on the way, can not carry out smoothly by warranty test.
