Comparison of biocidal and sporicidal effects of spark discharge plasma and mercury-vapor low pressure lamp radiations
نویسندگان
چکیده
In this work it was shown that the inactivation micromycets spore (fungi) to hot plasma radiation of self-sustained spark discharge on air is much more effectively than UVradiation mercury-vapor lamp. Though the discharge electrical power is 15 times and UVphotons flux 430 times more for mercury lamp than for spark discharge. Discussed method inactivation is very simple.
