El propósito de esta investigación fue comparar las propiedades físicas y químicas de dos biocarbones en diferentes condiciones de pirólisis. En un reactor pirolítico se obtuvieron los biocarbones a partir de cáscara de cacao (BCA) y estiércol bovino (BSB). Las condiciones de pirólisis fueron: 200ºC/60 minutos; 250ºC/30 minutos(E2); 300ºC/30 minutos. El biocarbón se dejó enfriar, para luego tamizar, proceder con los análisis. El mayor rendimiento del BCA fue de 35,56% y del BSB de 71,11%. Los valores de pH de todos los ensayos fueron altamente alcalinos con rangos de 8,23 – 10,04. En la prueba de hidrofobicidad los valores fueron: 65,73 s biocarbón de cacao y 228,3 s biocarbón de bovino. El mayor porcentaje de ceniza fue el estiércol bovino con 89,94 %. El análisis de Infrarrojo indicó picos de grupos funcionales carboxílicos en ambos biocarbones a 300ºC por 30 minutos.

Radiological analysis of mineral waters sampled from springs in the region of Sofia and Velingrad spa resort, and of bottled mineral, spring and table waters from other regions in Bulgaria was carried out as part of the overall monitoring of drinking waters in the country. Content of natural uranium was from 0.003±0.001 to 0.023±0.005 mg/l, gross alpha activity from ≤0.01 to 0.50±0.05 Bq/l and beta activity from ≤ 0.02 to 0.30±0.06 Bq/l. Concentration of indicators in all studied waters met the requirements, provided for in the Regulation for mineral, spring and bottled waters in Bulgaria (U ≤ 0.06 mg/l; gross alpha activity ≤ 0.5 Bq/l; gross beta activity ≤ 1 Bq/l). However alpha activity higher than 0.1 Bq/l, specified in the Regulation for drinking waters, was determined in the mineral water from Ovcha Kupel in Sofia (0.34 Bq/l) and in the bottled mineral water from Devin in the Rhodopes (0.49 Bq/l). Both water samples were further tested for Po-210. Content of Po-210 was under the derived concentration of 0.1 Bq/l laid down in the Regulation on drinking waters. In result of analyses carried out it was concluded the studied waters were not hazardous for human consumption in terms of radiology.
