Example Embodiment

[0015] The examples described in the present invention are to illustrate the present invention but not to limit the present invention. Any changes and adjustments within the equivalent meaning and scope of the present invention shall be considered within the scope of the present invention.

[0016] A graphene carbon filter material includes fruit shell activated carbon particles, and the gap at the bottom of the activated carbon contains 1% graphene oxide. The preparation method of graphene carbon filter material comprises the following steps:

[0017] Weigh the granular activated carbon, add graphene oxide dispersion after drying, the mass ratio of graphene oxide to water is 250:1, stir for 30 minutes, ultrasonic for 30 minutes, repeat twice and then dry.

[0018] best practice

[0019] For 2.000g of columnar activated carbon, add 0.5mL, 2mg / L graphene oxide dispersion, that is, the mass ratio is 250:1, repeat twice and then dry.

Abstract

The invention discloses a graphene carbon filtering material and a preparation method thereof. The material includes fruit shell active carbon granules, wherein 1% of graphene oxide is contained in gaps at bottoms of active carbon. The method includes the following steps of weighing granular and columnar active carbon, adding graphene oxide dispersion liquid after drying according to the mass ratio of 250:1, stirring for 30 minutes, conducting ultrasonic treatment for 30 minutes, and drying after repeatedly conducting stirring and ultrasonic treatment twice. By means of the filtering material, antibiotics in drinking water can be effectively removed, and the efficient filtering material is provided for current water treatment, especially the purification of drinking water.

Description

technical field [0001] The invention relates to a graphene carbon filter material and a preparation method thereof. Background technique [0002] The abuse of antibiotics has become a major problem at present, and relevant experts from the Ministry of Health even issued a warning that "antibiotics will destroy a generation in China", because antibiotics are generally used in large quantities in my country, and in many places, surface water bodies have also become carriers of antibiotics. The problem of overuse of antibiotics cannot be changed. Sooner or later, the water resources on which we depend will become life-threatening water. A recent academic report stated that 68 kinds of antibiotics were found in the detection of my country's surface water, and the concentration was relatively high. The source of drinking water in most areas of our country is groundwater, and the existing water treatment technology cannot completely remove antibiotics in water. Therefore, the harm...
