Table 2
Analysis of conclusion：
With the addition of triethanolamine functionalization graphene, properties substantially increase, but work as triethanolamine functionalization
After graphene reaches 9wt%, properties increase unobvious, from comparative example 1 as can be seen that triethanolamine function ought not be added
Effect is worst when graphite alkene, and reason is that triethanolamine functionalization graphene has very high adsorptivity as adsorbent
Ability, it is mainly attributed to the specific surface area of the dilute super large of graphite and the triethanolamine heavy metal chelating structure being modified.It is huge to compare table
Graphite dilute surface modification of area tertiary amine alcohol, considerably increases the strong avtive spot of adhesion, easily with heavy metal copper ion
Very strong complexing occurs, so as to have a higher adsorption capacity, and triethanolamine functionalization graphene be also equipped with it is very stable
Dispersiveness, from comparative example 2 as can be seen that using triethanolamine substitute triethanolamine functionalization graphene effect it is poor, reason
It is, triethanolamine has the non-pole of hydrophilic polar group and oleophylic as bleeding agent in the molecular structure of bleeding agent
Property group, the lubricant component parent of its lipophilic group and wax dirt the inside, but be a lack of complexing agent and can not remove the gold of metal surface
Belong to ion, in addition, also illustrating that triethanolamine functionalization graphene also retains the hydrophily and edible vegetable oil of triethanolamine.
From 9~embodiment of embodiment 13 and comparative example 2 as can be seen that when surfactant uses coco-nut oil fatty acid two
Best results when glycollic amide, sodium sulfate of polyethenoxy ether of fatty alcohol and lauryl sodium sulfate, reason are nonionic
Surfactant produces synergy with anion surfactant, can effectively reduce surface tension, reach preferable paraffin removal
Effect.
