preparation example Construction

[0089] The preparation method of the nanometer yttrium oxide that the present invention adopts comprises the steps:

[0090] Mix the ethanol solution of yttrium salt with sodium citrate, add sodium hydroxide solution under stirring conditions, and continue stirring for 10-20 minutes to obtain a suspension;

[0091] The suspension is subjected to solid-liquid separation, and the solid is collected for washing and drying;

[0092] Calcining the dried solid; the temperature of the calcination is 600±20° C., and the calcination time is 2-3 hours.

[0093] In a specific embodiment of the invention, the yttrium salt comprises yttrium nitrate.

[0094] The nano-yttrium oxide prepared by the above method has a certain particle size, shape, crystal form, etc., which further ensures the effectiveness of catalytic luminescence detection.

[0095] The preparation method of the nanometer yttrium oxide that adopts in following specific embodiment can comprise the steps: the In(NO of 0.766...

Embodiment 1

[0109] This example provides the use of figure 1 The detection device of shown butanone peroxide carries out the detection method of butanone peroxide, comprises the steps:

[0110] (1) adopt headspace gas distribution method preparation concentration to be the butanone peroxide gas of 200ppbv, as gas to be measured;

[0111] (2) Control the sampling valve to be in the energized state through the relay, start the sampling pump 11, and the gas to be tested is sent into the quantitative loop through the first channel a through the first valve port I and the second valve port II of the sampling valve, so that the gas to be tested Fill the quantitative loop and complete the sampling; the dry and clean carrier gas is sent from the second channel b through the third valve port III and the fourth valve port IV of the sampling valve into the quartz chamber to remove other gas impurities in the chamber; the carrier gas The flow rate is 240mL / min;

[0112] (3) Start the voltage regula...

Embodiment 2

[0120] This embodiment refers to the detection method of Example 1, the difference is that: under the conditions of detection wavelength of 425nm, reaction temperature of 80°C, and carrier gas flow rate of 240mL / min, the peroxidation concentrations of 30ppbv, 60ppbv and 200ppbv were respectively measured successively. Butanone gas, the gas sampling time of three concentrations is 20s, 50s and 80s respectively, the kinetic response curve obtained is as follows image 3 shown.

[0121] image 3 Among them, 1, 2 and 3 on the curve represent the kinetic response curves of the methyl ethyl ketone peroxide gas whose concentration is 30ppbv, 60ppbv and 200ppbv respectively.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a catalytic luminescent reactor, a detection device and a detection method for butanone peroxide. Background technique [0002] Butanone peroxide is a strong oxidizing agent with important applications in industry. Butanone peroxide is irritating to the respiratory tract, and can burn the skin and eyes, especially butanone peroxide is extremely unstable, and it will cause intense combustion or explosion when encountering a fire source or high temperature, friction, impact, etc. In recent years, butanone peroxide explosion accidents have occurred frequently, which has brought great harm to the safety of people's lives and property. The development of on-site and real-time on-line instrumentation methods for monitoring the concentration of methyl ethyl ketone peroxide plays an important role in preventing its harm. [0003] In view of this, the present invention is proposed. ...
