6、s the ships course and conventional loading goods.1.碳氢化合物测试（水溶性）Hydrocarbon test (water-soluble)a) 样品：在100毫升的试管中注入50毫升舱壁取样的甲醇样品，然后加入50毫升的蒸馏水，将混合物摇匀静置10分钟观察；sample: in 100 ml of the test tube injection 50 ml bulkhead sampling methanol samples, then add the 50 ml of distilled water, will shake mixture

7、 standing for 10 minutes observations;b) 标准：为便于比较观察，在100毫升的试管中注入50毫升标准甲醇试剂和50毫升的蒸馏水将混合物摇匀静置10分钟后作为标准试剂以作比较；standard: to facilitate comparative observation, in 100 ml of the test tube injection 50 ml standard methanol reagent and 50 ml of distilled water mixture will shake the quiet place after 10 mi

8、nutes as standard reagent for comparison,以下对应标准供参考。The corresponding standard for reference.0 ppm :和标准试剂同样清洗 0 PPM: and standard reagent also cleaning0.5 ppm 清晰度仅次于标准试剂 0.5 PPM definition after standard reagent1.0 ppm 轻微浑浊 1.0 PPM slight turbidity5.0 ppm 浑浊 5.0 PPM turbidity以上的对比最好在暗房中，衬以黑色的背景板，用电筒的

9、强光从试管的上部向下照射观察清晰度，以判断碳氢的含量是否满意。The contrast of above in the darkroom, line with black background plate, with a circle of light from the top of the tube downward exposure observation definition, to determine hydrocarbon content are satisfied. 2.氯离子的测试Chlorine ion test a) 样品：在100毫升的试管中注入50毫升舱壁取样的甲醇样品，

10、然后加入2毫升20%的硝酸溶液，摇匀后再加入2毫升2%硝酸银溶液，然后再加入46毫升的蒸馏水，将混合物摇匀静置10分钟观察；sample: in 100 ml of the test tube injection 50 ml bulkhead sampling methanol samples, and then add 2 ml of 20% nitric acid solution, shake well before add 2 ml of 2% silver nitrate solution, and then join 46 ml of distilled water, will s

14、ter and made into 15 degrees Celsius of cold water, will be provided with good water into a wide mouth vacuum flask to spare; Considering the dumping and waiting for the process water temperature rise and more than 15 degrees Celsius, it is suggested that when making up keep water temperature slight

15、ly lower than 15 degrees Celsius, such as 13, 14 degrees Celsius.b)样品：在50毫升的试管中注入50毫升舱壁取样的甲醇样品，然后滴入2毫升0.02%的高锰酸钾溶液并记录好滴入的时间，摇匀并盖好试管塞后置入盛有15摄氏度水的保温瓶中并盖好盖子，注意做好适当的固定以避免试管倒入水中造成污染而影响测试结果。B) sample: in 50 ml of the test tube injection 50 ml bulkhead sampling methanol samples, and then drop into 2 ml of

16、0.02% of potassium permanganate solution and record good drip into the time, shake up and cover the container with a placement test tube plug after 15 degrees Celsius water in the thermos flask and cover good cover, pay attention to the appropriate fixed in order to avoid tube into the water polluti

17、on caused by the influence and test results.c) 标准：在50毫升的试管中注入50毫升舱壁取样的标准纯净甲醇，然后滴入2毫升0.02%的高锰酸钾溶液并记录好滴入的时间，摇匀并盖好试管塞后置入盛有15摄氏度水的保温瓶中并盖好盖子，注意做好适当的固定以避免试管倒入水中造成污染而影响测试结果。C) standard: in 50 ml of the test tube injection 50 ml bulkhead sampling standard pure methanol, then drop it into 2 ml of 0.02% of po

18、tassium permanganate solution and record good drip into the time, shake up and cover the container with a placement test tube plug after 15 degrees Celsius water in the thermos flask and cover good cover, pay attention to the appropriate fixed in order to avoid tube into the water pollution caused b

19、y the influence and test results.4.其他Othera)高锰酸钾标准溶液的配备: 将0.1g的高锰酸钾晶体放入一个盛有500毫升蒸馏水的茶色避光瓶子中，摇匀后置于避光阴凉的地方，建议放于专用的小冰箱中。 equipped with potassium permanganate standard solution: 0.1 g potassium permanganate crystal in a container with a solution of 500 ml of distilled water to avoid light brown in the b

20、ottle, shake well before in a cool place to avoid light, Suggestions on the special small refrigerator.b)注意：高锰酸钾的测试要在避光的环境下进行，在每5-10分钟打开保温瓶的盖子查看颜色的变化的情况后尽快将保温瓶的盖子及时盖好；一切都正常的情况下标准纯净甲醇的变色时间应为120分钟左右，假设所供的标准甲醇高锰酸钾的变色测试时间仅为60分钟左右，那么舱壁取样的甲醇样品时间达到25分钟时则可以认为已达到了50分钟。其余情况按相同方法按比例计算即可；每一次使用相关的器具之前都要做好彻底的清洁工作

21、，而高锰酸钾测试时要求尤其高，试管的少许污染都会对实验的结果影响很大，试管更需彻底清洗，如需要使用前可以按如下步骤清洗：用20%的硝酸清洗一次，用自来水冲洗三次，紧接着用蒸馏水及标准甲醇再各清洗两次。B) note: potassium permanganate test to avoid light environment, in every 5-10 minutes to open the lid of the vacuum flask color change as soon as possible after the lid of the vacuum flask timely cov

22、er good; Everything is all right under the condition of the standard pure methanol color time should be 120 minutes, hypothesis for all standard methanol potassium permanganate discoloration testing time is only 60 minutes, then bulkhead sampling methanol sample time reached 25 minutes may think has

23、 reached 50 minutes. The rest of the situation in the same way scale calculation can; Each time the use of related instruments before do thorough cleaning, and potassium permanganate test requirements is particularly high, tube of a little pollution to the result of the experiment will influence, tube need more thoroughly clean, such as the need to use according to the step before cleaning: use 20% of nitric acid cleaning once, use tap water flushing three times, and then use distilled water and standard methanol to various cleaning twice.
