The measurement of the 226Ra, 232Th, 40K, and 238U were carried out using radioactive concentration value. The results showed that 226Ra = 39 Bq/kg, 232Th = 36 Bq/kg, 40K = 337 Bq/kg which are within acceptable limit for construction building. The radium equivalent activity for volcano ash is 116 ± 1 Bq/kg, means the exposure of y radiation is safe. Water from volcano ash may affected the aquatic ecosystem and human health which is not safe to be used as effluent due to high zinc, cadmium, lead, cyanide and sulphide and exceed the allowable limits. The mean particle size of the volcano ash was 121 pm. This volcano ash is almost dominated by quartz phase. SEM analysis showed that volcano ash had a plate-like structure similar to kaolin. The FTIR adsorption band showed the OH-, H-O-H, Si-O, Al-OH, and Si-O-Si and Si-O-M vibrations appeared in this volcano ash. The average total percentage of weight loss after being heated to 100WC was 15.85%. 2014-06-03T03:40:42Z 2014-06-03T03:40:42Z 2013-06 Article Revista de Chimie, vol. 64(6), 2013, pages 593-598 0034-7752 http://www.revistadechimie.ro/article_ro.asp?ID=3690 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35025 en SYSCOM 18 |
