Analytical Processing

The aim of this work was to develop technical analysis of wavelength dispersion X-ray fluorescence (WDXRF) and compare with technical neutron activation analysis (NAA). First, the standard of tin oxide (SnO) was ground into powder and mixed with boric acid (H3BO3) as binder at different weight. All of samples were investigated by WDXRF in normalize mode.The results indicated that the range can use to calibration at sample weight 0.2, 0.3 and 0.4 g. Next, the three SnO samples from different area (A, B and C) were ground, mixed with binder at ratio 0.2, 0.3 and 0.4 g and investigated by WDXRF in normalize mode. The results show tin (Sn) content of sample area A, B and C were 75.71, 74.61 and 71.01%, respectively. The result from NAA technique show Sn content of sample A, B and C were 79.36, 77.48 and 73.35%. The percentage error of WDXRF and NAA technique of the samples from the different area had 4.63, 3.70 and 3.19%. From the experiment as examined that the WDXRF technique could be improve process for determine chemical composition which one of choice for easy to used and low cost.

Impregnated Wood

AbstractThe present paper describes an energy-dispersive x-ray fluorescence method for measuring tin in bis(tri-n-butyl)tin-oxide impregnated wood. The proposed method is of the backscatter/fundamental parameter type. Its versatility, precision, and accuracy is demonstrated by analyses of eleven samples of sapwood of Baltic Redwood. The results obtained are compared with those from neutron activation analysis.

Bromine Determination

Abstract Organic compounds containing bromine, including methyl bromide, ethylene dibromide, and l,2-dibromo-3-chloropropane, have been used extensively for the fumigation of foods, or soils in which foods grow, making it necessary to determine residues of bromine and bromine-containing organic compounds. A large number of methods for the determination of bromine in foods, as organic, inorganic, and combined total bromide, have been developed. In methods for organic bromide, the bromine is converted to the inorganic form for measurement by titration, photometry, or other means. In recent years, instrumental methods have been developed in which the total bromine in the sample is determined, regardless of the state in which it exists. X-ray fluorescence and neutron activation analysis are the 2 instrumental methods used most widely. Residue data are presented for some typical bromine-containing samples.

We have examined the role of long-distance trade in Prehispanic Ecuador using X-ray fluorescence (XRF) and neutron-activation analysis (NAA) of obsidian artifacts from the archaeological sites of El Inga, Chobshi Cave and Site OGSE-46 on the Santa Elena Peninsula. Results indicate that two geological sources east of Quito, Yanaurco-Quiscatola and Mullumica, were the principal source of raw obsidian at these sites. We situate our findings within a broader archaeological context through a review of the literature and a discussion of an earlier provenience study undertaken by us. We express concerns about recent attempts to apply ethnohistoric models to early periods of Ecuadorian prehistory, and argue that despite early exploitation of the principal obsidian sources, long-distance trade in obsidian was initiated at a relatively late date and remained at a surprisingly low level in southern Ecuador during most of prehistory.
