Abstract

PURPOSE:To omit constant weight process before sucking in the water to be tested and make it possible to carry out measurement rapidly by using an aluminium foil vessel and storing this vessel and filter paper in a desiccator. CONSTITUTION:An aluminium foil vessel and glass fiber filter paper are stored in a desiccator to omit constant weight handling before testing water. Next they are taken out of the desiccator and weighed, then a certain amount of specimen is taken by, for instance, a mess cylinder or other measuring instruments, and the specimen is filtered. Next, after the specimen is dried for one hour in a dryer at 105-110 deg.C, it is cooled in the desiccator for 10min, and (glass fiber filter paper)+(aluminium foil vessel)+(remnant) are weighed, and the amount of the suspensoid is calculted by: ss (ppm)=remnant (mg)X1,000/specimen(ml). It is thereby possible to omit constant weight measurement process of filters before filtering of specimens.

時間を要するという欠点がある。The method for measuring suspended solids is specified in Jraxo102. This measurement method is the glass fiber paper method (GFP), and is expressed in a flow sheet as shown in #1. However, since this method is a gravimetric method, it has the disadvantage that it takes a long time to constant the weight of the filter before and after filtering the sample.

測定方法を確立するＫあたって検討した事項について詳
しく説明する。In the measurement method according to the present invention, an aluminum foil container is used instead of the glass filter used in the conventional method, and the aluminum foil container and glass fiber filter vapor are stored in a desiccator for inspection. The feature is that the constant volume operation before water suction is omitted. Hereinafter, the matters considered in establishing the measurement method of the present invention will be explained in detail.

まず、ＪＩｇ　Ｋ規定されている方法によれば、ろ紙を

てみた。第１表Ｋ。First, according to the method prescribed by JIgK, before drying the filter paper, wash it with water several times and suction it, then dry it.
It says that drying for hours is K, but in order to find out whether that is necessary, we weighed a filter paper that had not been washed with water, then washed the filter paper with water and weighed it, and compared the results. I tried it. Table 1 K.

その結果を示す− この実験結果から、ろ紙を水で洗浄する必要はないこと
がわかった。The results are shown - From the results of this experiment, it was found that there is no need to wash the filter paper with water.

次にガラス濾過器は非１に恒量になりＫくい。Next, the glass filter becomes non-uniform and has a constant weight.

それ故に、ガラス濾過器に代えてアルミ箔容器を作り、
グラスファイバーフィルターペーパーをこのアルミ箔容
器の中に入れ、恒量操作を試みた。Therefore, we made an aluminum foil container instead of a glass filter.
A glass fiber filter paper was placed in this aluminum foil container and a constant weight operation was attempted.

間がかかるという問題を、アルミ箔容器に代えたことＫ
よって解決した。The results showed that aluminum foil containers are lighter than glass containers, do not break, and are easier to maintain a constant weight. The foil container reached a constant weight after 2 times. This means that by putting the Arun foil container + glass fiber filter paper in the dryer and drying it once and leaving it to cool, a constant weight value can be obtained. As a result, the problem of the time required for constant weight determination using the gravimetric method was solved by replacing it with an aluminum foil container.
So it was resolved.

次に、乾燥時間を２時間にしなければならないか否かに

か比較してみた、第２表に、その結果を示す。Next, we investigated whether the drying time should be set to 2 hours. According to the method prescribed by JIB,
Although it is supposed to dry for 2 hours using 105-tlo a, we compared the effect of drying for 1 hour, which is half of this, and the results are shown in Table 2.

この結果から、１時間乾燥した場合と、２時間乾燥した

時間の乾燥で充分であることがわかった。From this result, the average value of the difference between when drying for 1 hour and when drying for 2 hours! is -α181IP, which is within the constant weight value, and the rate at which the weight reached constant weight is 100-. From this, even if you do not dry at 105-110°0 for 2 hours, 1
It was found that drying time was sufficient.

果を示す。In addition, an aluminum foil container and a glass fiber filter paper were stored in a desiccator to determine whether or not it was necessary to dry them before use. Table 3 shows the results.

重量に変化がないということもわかった。From the results of this experiment, it was found that the filter paper was not dried to a constant weight, but was stored in a desiccator and directly weighed, and was used in good condition. It was also found that there was no change in weight for 1 to 120 hours if the material was left to cool after drying in a desiccator.

The weight at this time is assumed to be at. Subsequently, a fixed volume of sample is collected using, for example, a graduated cylinder,
Filter this. Here, washing of the filter paper with water before suctioning the sample water is omitted. Next, in the dryer 105-110
Dry at 0 temperature for 1 hour, then cool in a desiccator for 10 minutes, and weigh the filter paper (glass fiber filter paper) + alkali container + leftover e The weighed value at this time is defined as bt.
