Experimental researches on the early growth characteristics of BaMoO_4 thin film by using electrochemical technique;

In the research experiments on the early growth characteristics of BaMoO_4 thin film deposited by constant-current electrochemical technique,some important experimental phenomena were discovered.

Strontium molybdate(SrMoO_4) thin films with scheelite-structure were prepared directly on the metal molybdenum substrates by constant current electrochemical technique with emphasizing on the study of the growth characteristics of the films.

The electrochemical technology and immobilization technology were combined to treat the pulping and papermaking wastewater.

In this paper,the basic methods of electrochemical technology for the treatment of environmetal pollution are introduced.

The application of electrochemical technology in development of cleaner production processes,preparation of cleaner products,treatment of wastewater and waste gas,remediation of polluted soil and monitoring of environmental pollutants is presented.
