Embodiment 1
[0052] step 1:
[0053] Dissolve Nile Red in acetone;
[0054] Step 2:
[0055] Divide bottled water of three different brands of X, Y, Z into three parts: each part is dyed with Nile Red;
[0056] Step 3:
[0057] Filter the three types of bottled water after Nile Red dyeing;
[0058] Step 4:
[0059] Micro-infrared analysis of the filtered particles, scanning electron microscope + X-ray energy spectrometer analysis;
[0060] Step 5:
[0061] Perform component analysis and classification of the particulate matter after component analysis, and analyze possible sources.
[0062] The analysis results are shown in Table 1.

Embodiment 2
[0091] Step 1: Pour Nile Red powder into acetone to dissolve it to prepare a solution with a concentration of Nile Red of 0.1 mg / mL; prepare the filter membrane, clean it and analyze it under the microscope. If there are particles that affect the analysis results, continue to clean and clean. The filter membrane is placed in a clean petri dish.
[0092] Step 2: Filter 10 mL of acetone solution and 10 mL of Nile Red solution on a 1 μm filter membrane, respectively, and analyze particles and components.
[0093] Step 3: Pour the Nile Red solution into the pressure tank of the spray gun, filter through the built-in 0.45μm filter membrane of the filter gun, collect 10mL filtrate and filter it on the 1μm filter membrane, analyze the particles and components; (blank test)
[0094] Step 4: Prepare water samples a, b, c, d, e, 1.5L / bottle, 2 bottles each; clean the outer wall of the bottle with deionized water filtered by a 0.45μm filter membrane before testing to avoid introducing impuritie...
