Abstract

The use of hydroxide compounds as CO2 absorbents for Measurement of Carbon-14 in Coral Reef Sample fromSpermonde Archipelago. This research aimed to determine the age of coral reef sample of Spermonde Archipelago by measuring the activity of carbon-14 using the method Liquid Scintillation Counting (LSC). The coral reef sample was collected in Langkai Island. The research was conducted by following steps of sample preparation, the CO2 absorption using the hydroxide solutions (KOH and NaOH). The measurement of the carbon-14 activities was performed using the Liquid Scintillation Counter (LSC) Hidex 300 SL. The research results indicated that the absorption capacities of KOH and NaOH were 0,450 and 0,425 mol CO2/mol hydroxide respectively. The specific activity of coral reef sample using absorbent KOH and NaOH were 14.51; and 14.57 DPM/g C, respectively.The age of coral reef sample, which was calculated based on the specific activity values using the absorbents KOH and NaOH were 436.13; and 403.61years, respectively.
