Abstract
The present invention be a kind of active powdered carbon to the rapid assay methods of Methylene blue adsorption, concretely comprise the following steps：(1) 1 3g methylene blues are weighed to be dissolved in 1000ml running water, is stirred well to and is completely dissolved, be made into methylene blue solution；(2) methylene blue solution that 10 12ml prepare is pipetted with graded tube to be placed in colorimetric cylinder；(3) weigh 0.1 2g activity powdered carbon to add in colorimetric cylinder, once shaked by upper and lower mode, number is shaked when recording initial decolourize.When present invention measure activated carbon is to the decolorizing ability of methylene blue, the instrument price used is low, only needs one hour from the measure that is formulated into of reagent, rapidly and efficiently, simple and fast.
Description
Technical field
Measure field the present invention relates to active powdered carbon to Methylene blue adsorption, more particularly to a kind of active powdered carbon is to Asia
The rapid assay methods of methyl blue decolorizing ability.
Background technology
The intrinsic loose structure of activated carbon can decolourize to methylene blue solution, and decolorizing ability represents the work of activated carbon decolorizing
Property height, activated carbon decolorizing power is measured now with a variety of National Standard Methods.
Including the measure (GB/T7702.6-2008) of ature of coal granular activated carbon test method methylenum careuleum adsorptive value, wooden work
The measure (GB/T12496.10-1999) of property charcoal test method methylene blue adsorption value, methylene blue adsorption value (YFGL-GY-B-
0033) etc..But these measuring methods are measured using spectrophotometer, decolorizing ability is reacted by specific test value, point
Light photometer price is higher；And need to prepare the reagent of correlation in advance, wherein a reagent sodium thiosulfate needs to carry the last week
Prepared, and stood, this process needs 4-5 days；Sample is also required to pre-treatment, is ground, sieves and dries, this
It is more than hour to need two for individual process；Also need to last experimental period one day.
For the method for traditional National Standard Method measure activated carbon decolorizing power above-mentioned, how measure rapidly and efficiently into
For Research Points.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of active powdered carbon is provided to the quick of Methylene blue adsorption
Assay method.
The present invention to achieve the above object, using following technical scheme：
A kind of active powdered carbon concretely comprises the following steps to the rapid assay methods of Methylene blue adsorption：
(1) 1-3g methylene blues are weighed to be dissolved in 1000ml running water, is stirred well to and is completely dissolved, be made into methylene blue
Solution；
(2) methylene blue solution that 10-12ml prepares is pipetted with graded tube to be placed in colorimetric cylinder；
(3) weigh 0.1-2g activity powdered carbon to add in colorimetric cylinder, once shaked by upper and lower mode, recorded
Number is shaked during initial decolouring.
The volume of the colorimetric cylinder is 25ml.
When being shaked after active powdered carbon addition colorimetric cylinder, take multiple samples while shaked, judge decolorizing ability
It is excellent.
Carried out when weighing methylene blue, active powdered carbon using assay balance, the precision of assay balance is adjusted to 0.001.
The beneficial effects of the invention are as follows：When present invention measure activated carbon is to the decolorizing ability of methylene blue, the instrument valency that uses
Position is low, only needs one hour from the measure that is formulated into of reagent, rapidly and efficiently, simple and fast.
