Abstract

Nitrogen ions have been generated in the air by   corona glow discharge plasma.  The unipolar current sturation  of  Sigmond has been observed and nitrogen ions were used for enrichment of nitrogen in compost of  palm oil empty fruit bunches. Generator of ions was a positive corona discharge plasma with multi point to plane electrodes configurations and by using  a DC voltage source of 6.8 kV and 8 mA. In the glow discharge plasma condition, the  nitrogen ions were produced in air. Implantation of nitrogen ions can increase the levels of nitrogen in the compost. The highest percentage of nitrogen is obtained in the series of experiment for time of radiation was 100 minutes. The amount  of mass percentage of nitrogen in the enrichment  compost was  (3.4 ± 0.3) % and  we compare with compost control without ions radiation was 1.1 % (mass percentage). It can be concluded that the increasing of nitrogen content in the compost can be done by almost 300 % .

 

Key words : corona glow discharge plasma, compost, nitrogen ionic
