ANALISA SECARA LANGSUNG UNSUR-UNSUR ELEMENTER DI DALAM CAIRAN DENGAN METODE LASER INDUCED BREAKDOWN SPECTROSCOPY

Author :
Agus Rubianto 




ABSTRAK

Telah dilakukan analisa unsur-unsur elementer pada larutan dengan metode LIBS Laser Induced Breakdown Spectroscopy dengan sumber radiasi Nd-YAG laser. Larutan terbentuk dari air aqua ditambah dengan beberapa unsur pencemar Cu Ca dan NaCl. Metode ini merupakan metode yang sangat akurat dibandingkan metode kimia yang lain sebab sampel tidak mengalami perlakuan awal. Konsentrasi pencemar dapat diukur dengan orde sampai dengan 5 ppm. Dari penelitian ini didapatkan juga 4 spektrum hydrogen di air yang tidak diduga sebelumnya.


ABSTRACT

An elementary elements has been analyzed at condensation by the method LIBS Laser of Induced Breakdown Spectroscopy with the source of radiation Nd-Yag laser. Condensation formed of an aqua waters added with a few elements of Cu Ca and NaCl. This Method is very accurate comparing other chemical method because samples do not early use the treatment. Measurable concentration of elements is about with the order of up to 5 ppm. From this research is got also 4 spectrum hydrogen in water which none anticipated previously.
