Embodiment 1
[0013] A rapid detection method for coal tar component content, comprising the steps of:
[0014] Step 1: Get 0.0501 grams of commercially available refined naphthalene (naphthalene content 99.5%), weigh to 0.0001 grams, 50 milliliters of xylene, put refined naphthalene and xylene in a 50 milliliter volumetric flask, and make 50 milliliters of naphthalene after dissolving Standard solution, spare;
[0015] Step 2: adopt gas chromatograph, analyze naphthalene standard solution, record the result, draw the peak area of naphthalene as 140;
[0016] Step 3: Take 0.5010 g of coal tar, weigh to 0.0001 g, and 25 ml of xylene, put the coal tar and xylene into a volumetric flask, heat to 50°C, and use a heating ultrasonic instrument to help the coal tar sample dissolve completely. After dissolving, add xylene to make the solution constant to 50 milliliters to prepare a sample solution, which is cooled and set aside;
[0017] Step 4: the sample solution obtained in the step 3 is fil...
Embodiment 2
[0020] A rapid detection method for coal tar component content, comprising the steps of:
[0021] Step 1: Get 0.0505 grams of refined naphthalene (naphthalene content 99.5%), weigh to 0.0001 grams, 50 milliliters of xylene, put refined naphthalene and xylene in a 50 milliliter volumetric flask, dissolve as a naphthalene standard solution, and set aside;
[0022] Step 2: adopt gas chromatograph, analyze naphthalene standard solution, record the result, draw the peak area of naphthalene as 145;
[0023] Step 3: Take 0.5100 g of coal tar, weigh to 0.0001 g, and 25 ml of xylene, put the coal tar and xylene into a volumetric flask, heat to 80°C, and use a heating ultrasonic instrument to help the coal tar sample dissolve completely. After dissolving, add xylene to make the solution constant to 50 milliliters to obtain a sample solution, which is cooled and set aside;
[0024] Step 4: Filter the sample solution prepared in step 3 with a 0.45um microporous organic filter membrane....
Embodiment 3
[0027] A rapid detection method for coal tar component content, comprising the steps of:
[0028] Step 1: Get 0.0510 grams of refined naphthalene (naphthalene content 99.5%), weigh to 0.0001 gram, 50 milliliters of dimethylbenzene, put refined naphthalene and dimethylbenzene in a 50 milliliter volumetric flask, obtain 50 milliliters of solution after dissolving, as Naphthalene standard solution, spare;
[0029] Step 2: adopt gas chromatograph, analyze naphthalene standard solution, record the result, draw the peak area of naphthalene as 150;
[0030] Step 3: Take 0.5060 g of coal tar, weigh to 0.0001 g, and 25 ml of xylene, put the coal tar and xylene into a volumetric flask, heat to 65°C, and use a heating ultrasonic instrument to help the coal tar sample dissolve completely. After dissolving, add xylene to make the solution constant to 50 milliliters to prepare a sample solution, which is cooled and set aside;
[0031] Step 4: Filter the sample solution prepared in step ...
