SPRAY DRYING METHOD FOR PREPARING CANDIDATE OF SALT WATER
REFERENCE MATERIAL
The present disclosure belongs to the field of testing tech- nologies of geological experiments, and in particular, to a spray drying method for preparing a candidate of a salt water reference material.
A salt water reference material is prepared from natural salt water and used for monitoring and controlling in the process of salt water analysis. An existing process is sampling salt water and then performing sealed preservation. A salt water reference material prepared according to the existing process has poor sta- bility and is difficult to transport.
To overcome the above defects in the prior art, an objective of the present disclosure is to provide a spray drying method for preparing a candidate of a salt water reference material, which is easy to operate. A finished product prepared according to this method has high stability and is easy to preserve.
To achieve the above objective, the present disclosure adopts the following technical solution:
A spray drying method for preparing a candidate of a salt wa- ter reference material is provided, including the following steps: step 1: filtering salt water with a 25 um filter membrane, and accurately pipetting 50 mL of filtered salt water to a glass colorimetric tube; step 2: turning on an air exhauster of a laboratory mini spray dryer, setting power of the air exhauster to 90 3, setting inlet temperature of the spray dryer to 125°C, turning on a heater of the spray dryer, turning on a compressor and a peristaltic pump after the inlet temperature of the spray dryer reaches 125°C, and cleaning a drawing nozzle, where outlet temperature of the spray dryer is 140°C when the inlet temperature of the spray dryer reach- es 125°C; step 3: drawing the filtered salt water sample into the spray dryer by using a ruby drawing nozzle, and spray-drying the sample; and step 4: taking out the spray-dried sample, and performing prompt sealing for preservation, to obtain a finished product.
In step 2, a compression speed of the compressor is set to 400 L/h, and a working ratio of the peristaltic pump is set to 25%.
Compared with the prior art, in the present disclosure, a candidate of a salt water reference material is prepared by using the spray drying method, such that a process is easy to control, and a finished product is convenient to preserve.
FIG. 1 is a flowchart of a process according to the present disclosure.
The implementations of the present disclosure are described below in detail with reference to the accompanying drawings and examples.
A spray drying method for preparing a candidate of a salt wa- ter reference material is provided. Referring to FIG. 1, the meth- od includes the following steps:
Step 1: Filter salt water with a 25 pm filter membrane, and accurately pipette 50 mL of filtered salt water to a glass colori- metric tube.
Step 2: Turn on an air exhauster of a laboratory mini spray dryer, set power of the air exhauster to 90 %, set inlet tempera- ture of the spray dryer to 125°C, turn on a heater of the spray dryer, turn on a compressor (whose compression speed is set to 400
L/h) and a peristaltic pump (whose working ratio is set to 25%) after the inlet temperature of the spray dryer reaches 125°C, and clean a nozzle, where outlet temperature of the spray dryer is 140°C when the inlet temperature of the spray dryer reaches 125°C.
Step 3: Draw the filtered salt water sample into the spray dryer by using a ruby nozzle, and spray-dry the sample.
Step 4: Take out the spray-dried sample, and perform prompt sealing for preservation, to obtain a finished product.
Before use, the finished product of the candidate of the salt water reference material can be reduced to a twice diluted solu- tion of original salt water by opening a sealed packaging bag and quantitatively adding the finished product in 100 mL of distilled water for dissolution.
The following test data is obtained when the sample is de- tected according to an inductively coupled plasma atomic emission spectrometry and a volumetric method:
Concentration of lithium: 131 mg/mL
Concentration of strontium: 25 mg/mL.
