Abstract
It is a kind of quickly nanometer carbon solution be concentrated and nanometer carbon deposition and isolated method belong to prepare nano-sized carbon field.Nanometer carbon solution pH less than 2.4 solids level concentration 0.1%-5%, by the way that ceramic membrane is repeatedly concentrated, so that nanometer carbon content increase becomes that nanometer carbon solution is concentrated, and pass through the addition of cellulose ether or ammonium hydrogen carbonate, so that the nano-sized carbon complex-precipitation in solution containing negative potential, forms transparent clear liquid.Concentrate can form salt-free nano-carbon powder by processing again, can be widely applied to different field by repeatedly concentration and precipitating, the sour clear solution of output after working process, can be used for medical treatment or agriculture sterilizing or fresh-keeping.This concentration and separation coprecipitation mode simple process, environmental protection, low energy consumption can big industrial production.
Description
Technical field
It is a kind of quickly nanometer carbon solution be concentrated and nanometer carbon deposition and isolated method belong to prepare nano-sized carbon field.
Background technique
In the prior art applicant do not find can rapid nano carbon solution concentration and nanometer carbon deposition and separate
Method.The present invention cleverly applies ceramic membrane and is repeatedly concentrated, and at the same time by the addition of cellulose ether or ammonium hydrogen carbonate,
So that the nano-sized carbon complex-precipitation in solution containing negative potential, there is very big industrial utility value.And output after working process
Sour clear solution, can be used for medical treatment or agriculture sterilizing or fresh-keeping.
Summary of the invention
A method of quickly the concentration of nanometer carbon solution and nanometer carbon deposition and separation, it is characterised in that: pH is small
In the nanometer carbon solution of 2.4 solids level concentration 0.1%-5%, by the way that ceramic membrane is repeatedly concentrated, so that nanometer carbon content increases
Become that nanometer carbon solution is concentrated, and by the addition of cellulose ether or ammonium hydrogen carbonate, so that containing the nanometer of negative potential in solution
Carbon complex-precipitation forms acid transparent clear liquid.
Further, the additional amount of cellulose ether or ammonium hydrogen carbonate is 0.1-1g/L nanometers of carbon solutions, and the nano-sized carbon is molten
Liquid is nanometer carbon solution of the initial pH less than 2.4 solids level concentration 0.1%-5%.
Concentrate can form salt-free nano-carbon powder by processing again by repeatedly concentration and precipitating, can be extensive
Applied to different field, the sour clear solution of output after working process can be used for medical treatment or agriculture sterilizing or fresh-keeping.It is this
It is concentrated and separated coprecipitation mode simple process, environmental protection, low energy consumption can big industrial production.
Specific embodiment
250 liters of nanometer carbon solution that pH is 2 solids level concentration 5g/L, by being that 10nm ceramic membrane is repeatedly dense to aperture
Contracting, is concentrated into 5 liters of nanometer carbon solutions, is obtaining carbon nanopowder by heating or spray drying.
Cellulose ether or ammonium hydrogen carbonate is added by the transparent clear liquid of acidity separated, can be separated after complex-precipitation
Liquid out forms acid solution of the transparent pH less than 2.4.
The Water absorption of cellulose ether can reach 4000-20000 multiple, or ammonium hydrogen carbonate is added, and be of good performance
Food grade additives.The additional amount of cellulose ether or ammonium hydrogen carbonate is 0.1-1g/L, is further 0.3-0.5g/L, more into one
Step is 0.3-1g/L.
