Summary
As the development of our society, industrial waste, pesticide residues, municipal solid waste are threatening our life quality and bringing harm to our health. So we should protect our environment with the help of high technologies, such as, liquid chromatography mass spec.
Body
The application of liquid chromatography mass spec in environmental protection
The wide use of LC Mass Spec in environmental protection has contributed a lot to water pollution, air pollution, noise pollution, radioactive pollution.
Among the pollution of environment, water contamination is the most widely andhazardous for us. The main factors of water contamination are like following:
Inorganic contaminants: various toxic metals and their oxides, acids, alkalis, salts, sulfides and halides.
Organic pollutants: pollutants plastics, synthetic fibers, synthetic rubber, detergents, dyes, solvents, paints, pesticides and so on.
Why can LC Mass Spec be widely used in this aspect? It has its own advantages. It has the ability of good separation efficiency; selectivity is high; high sensitivity and analysis speed. Besides these advantages, the use range ofLC Mass Spec is expanding and it also can be used for the preparation of samples.
LC technology in the process of nitro-benzene degradation
This application can be a reference to the analysis theory of degradation nitro-benzene reduction.
There are some mistake we may make during this process and we also put up with some solutions for you.
Inadequate samples
As for this mistakes, we can enhance the matrix environmental polar. If the sample in an organic solvent, we can change solvent into water or a buffer solution in order to ensure the normal retention.
Incomplete purification
Whashing it with different solvents and buffer solution to remove the interferences without eluting the target analyte.
Incomplete eluting
Using stronger eluent or adding strong elution solvent to the eluent.
Unstable recovery
Using the most effective elute or adding all kinds of buffer solutions in order to find a better elution solvent to elute all of the target analytes.
This is a brief introduction to the application of LC Mass Spec in the
environmental protection.
