Content of 16 essential elements was determined in three kinds of frankfurters by atomic absorption spectrophotometry. The element content of frankfurter batter was compared with processed frankfurters. There were larger (P<0.05) amounts of sodium in beef; colbalt, manganese and sodium in chicken; and manganese, potassium and sodium in meat frankfurters (beef and pork) after processing. Chicken samples contained less (P<0.05) chloride and potassium after processing. All frankfurters studied were superior sources of iron and zinc and fair sources of potassium when compared to other foodstuffs. Element retention ranged from 80.9% to over 100%. Data suggest that processing had minimal effects on element loss.

Process Element

Ten essential elements were determined in dry and canned butter beans (Phaseolus limensis L.) by atomic absorption spectrophotometry. Samples were taken at different stages during the canning process to determine where changes in element content occurred. The content of each sample was compared statistically to other samples taken within the process. Element retention, excluding chloride and sodium, ranged from 51 to 84% on a dry weight basis, and 14 to 24% on wet weight basis.

Ten essential elements were determined in dry and canned chick peas (Cicer arietinum L.) by atomic absorption spectrophotometry. Samples were taken at different stages during the canning process to determine where changes in element content occurred. The content of each sample was compared statistically to other samples taken within the process. Element retention, excluding chloride and sodium, ranged from 12 to 127% on a dry weight basis and 4 to 45% on wet weight basis.

Abstract Water, chelate, and acid techniques were compared for the extraction of iron and zinc from fertilizer samples. The water and chelate extractions were studied to offer an alternative to the official final action acid extraction, 2.098(a)–(c); atomic absorption spectrophotometry was the determinative step. The results for 10 samples from 24 laboratories were examined statistically and were sufficiently reproducible for widespread use of the methods. Statistical treatment of the data from the proposed methods compared favorably with that from the official method. Both the water and chelate extraction techniques have been adopted as official first action, supplementary to 2.098.

Lipstick or lip dye is a cosmetic dose that serves to coloring, decorative the lips, as a moisturizing material and protect the lips from exposure the sun to provide optimum results. Lipstick should not contain chemicals such as lead (Pb) because the Pb is a heavy metal that is very dangerous when continuously used on the skin, because it will be absorbed into the blood and attack the body organ causing the onset of disease. According to BPOM that the lead rate on the lipstick does not exceed the permissible limit of 20 mg/kg or 20 ppm.This research aims to know the levels contained in the samples are 4 brands of matte lipstick that are sold in the Aceh market in Banda Aceh City with the method of atomic absorption spectrophotometry (AAS). The results showed that on the 4 brands of lipstick matte contain heavy metal lead (Pb) with a rate still qualified allowed by BPOM  is samples A, B, C, and D, respectively at 0.24 ppm; 0.10 ppm; 2.87 ppm and 1.32 ppm, so that the 4 brands of lipstick matte are still used.

Pewarnaan pada proses produksi kain sasirangan menghasilkan limbah yang mengandung logam berat, diantaranya adalah timbal (Pb2+) dan kadmium (Cd2+). Penelitian ini bertujuan untuk mengetahui pengaruh proses fitoremediasi terhadap konsentrasi logam Pb2+ dan Cd2+ dari limbah cair industri sasirangan di Kalimantan Selatan, serta mengetahui pertambahan berat basah eceng gondok. Eceng gondok yang sudah dibersihkan dan diaklimatisasi ditanam dalam reaktor berisi larutan limbah dengan konsentrasi 3% (v/v); 9% (v/v); dan 15% (v/v). Sampel diambil setiap 2 hari sekali sebanyak 100 ml dan dianalisis menggunakan AAS (Atomic Absorption Spectrophotometry). Hasil penelitian ini menunjukkan bahwa konsentrasi logam Pb2+ dan Cd2+ dalam limbah setelah proses fitoremediasi terjadi penurunan. Kadar Pb2+ pada konsentrasi 3% (v/v) semula 0,197 ppm menjadi 0,062 ppm, pada konsentrasi 9% (v/v) semula 0,200 ppm menjadi 0,077 ppm dan untuk 15% (v/v) adalah 0,225 ppm menjadi 0,093 ppm. Sedangkan untuk Cd2+ konsentrasi 3% (v/v) semula 0,110 ppm menjadi 0,059 ppm, konsentrasi 9% (v/v) adalah 0,127 ppm menjadi 0,045 ppm dan untuk konsentrasi 15% (v/v) semula 0,144 ppm menjadi 0,047 ppm.

Abstract The official first action AOAC method for the spectrophotometric determination of biuret in urea, 2.072—2.074, was compared with official first action AOAC method 2.C01-2.C03 (atomic absorption spectrophotometry), 2 simplified versions of 2.072-2.074, and modified versions of 2 alternative procedures of the International Organization for Standardization. Three synthetic urea samples (0.3, 1.4, and 3.0% biuret) and 1 commercial urea sample (1.0% biuret) were analyzed. The methods proved to be equivalent and none showed a definite advantage over 2.072-2.074. The purification of biuret and the interference by ammonia are also discussed.
