Examples
Embodiment 1
[0017] Soak attapulgite clay raw ore in water for 24 hours, filter to remove impurities such as quartz sand in the raw ore, concentrate and dry the filtrate to obtain pure attapulgite clay; stir 10g attapulgite clay and 0.5g rhodamine 6G evenly, and transfer to a ball mill tank, ball milled at 300 rpm for 3 hours, sieved, washed with water until the eluate was colorless, and dried at 60°C to obtain rhodamine 6G fluorescent attapulgite clay; the excitation of the rhodamine 6G fluorescent attapulgite clay spectra and emission spectra such as figure 1 , 2 shown.
Embodiment 2
[0019] The purification of attapulgite clay is the same as example 1; 10g attapulgite clay, 0.01g rhodamine 6G and 0.5g polyethylene glycol are stirred evenly, move into ball mill jar, ball mill reaction 8 hours under 100 rev / mins, sieve, Wash with water until the eluate is colorless, and dry at 60°C to obtain rhodamine 6G fluorescent attapulgite clay with higher viscosity.
Embodiment 3
[0021] The purification of attapulgite clay is the same as example 1; 10g attapulgite clay and 0.25g eosin pigment are stirred evenly, moved into a ball mill jar, and ball milled at 800 rpm for 1 hour, sieved, washed until the eluate is free color; dried at 60°C to obtain eosin fluorescent attapulgite clay.
