Abstract

The invention discloses a preparation method of an adsorption material. The preparation method comprises the following steps: (1) providing a porous adsorption material; (2) immersing the porous adsorption material in a sodium thiosulfate solution with the concentration of 5g / L to 10g / L for 20min to 60min; (3) draining the porous adsorption material adsorbed by the sodium thiosulfate, and drying at 37 DEG C to 40 DEG C for 24h to 48h. The invention further discloses a water sample collection bag with the adsorption material. The preparation method disclosed in the invention has a simple preparation process and the whole process is finished at a low temperature and low pressure and is not dangerous; the sodium thiosulfate solution does not need to be prepared every time that a water sample is taken and large-batch production of the adsorption material can be realized; the sodium thiosulfate in the water sample collection bag exits in a solid form and can be stored for a long period; the bag is small in size, light in weight and convenient to carry, so that the bag is convenient to carry when people go out to sample in a large batch; only a bottle cap needs to be opened when the bag is used; the bag can be used immediately when being taken and does not need to be prepared in advance, so that the bag is convenient to utilize.

Description

technical field [0001] The invention belongs to the technical field of water quality detection, and in particular relates to a preparation method of an adsorption material and a water sample collection bag. Background technique [0002] With the rapid development of social economy and the advancement of industrialization and urbanization, the problem of water pollution is becoming more and more serious. At the same time, people have higher and higher requirements for the quality of drinking water. At present, there are a large number of microorganisms in drinking water in our country, among which some microorganisms such as bacteria and Escherichia coli have a certain threat to people's health. Inspection, after the inspection reaches the standard, it can be delivered to the end user. [0003] At present, the most common way to collect microorganisms in drinking water is to use high-temperature sterilized and sealed glass bottles to collect water samples on site, and then t...
