Problems solved by technology

But these measurement methods adopt spectrophotometer to measure, reflect the decolorization power by specific test value, spectrophotometer price is higher; And need to prepare relevant reagent in advance, wherein one reagent sodium thiosulfate needs to prepare one week in advance, and static This process takes 4-5 days; the sample also needs to be pre-treated, grinding, sieving and drying, this process takes more than two hours; the final experiment cycle needs one day

Abstract

The invention discloses a method for fast measuring an activated carbon powder decolourization capacity to methylene blue. The method comprises (1) weighing 1 to 3g of methylene blue, dissolving the methylene blue in 1000ml of tap water and fully stirring the solution until complete dissolution to obtain a methylene blue solution, (2) transferring 10 to 12mL of the methylene blue solution into a colorimetric tube through a graduated tube, and (3) weighing 0.1 to 2g of activated carbon powder, adding the activated carbon powder into the colorimetric tube and carrying out vertical jolting and recording the jolting times when initial decolorization. When the activated carbon powder decolourization capacity is measured, the used instrument has a low price, time from regent preparation to measurement is 1h, measurement is fast and efficient and the process is simple and fast.

Description

technical field [0001] The invention relates to the field of determination of the decolorization power of activated carbon powder to methylene blue, in particular to a rapid determination method of the decolorization power of activated carbon powder to methylene blue. Background technique [0002] The inherent porous structure of activated carbon can decolorize the methylene blue solution. The decolorization power represents the decolorization activity of activated carbon. Now there are many national standard methods to measure the decolorization power of activated carbon. [0003] Including, coal-based granular activated carbon test method for the determination of methylene blue adsorption value (GB / T7702.6-2008), wooden activated carbon test method for the determination of methylene blue adsorption value (GB / T12496.10-1999), methylene blue adsorption value (YFGL- GY-B-0033) and so on. But these measuring methods adopt spectrophotometer to measure, reflect decolorization p...
