Abstract In this study, the silver extraction potential from waste x-ray films using sodium hydroxide and nitric acid was studied. Sodium of different concentrations were used as stripping solutions to determine optimum leaching concentration. Optimum time temperature also investigated by varying temperatures, respectively. The stripped analysed for concentration Flame Atomic Absorption Spectro...

Durian seed flour can be used for the manufacture of food products such as sticks and steamed sponges. Sticks sponge cake are foods that many people like from children to adults. is rich in minerals including magnesium, potassium, calcium phosphorus. This study aims determine content phosphorus durian using Atomic Absorption Spectrophotometer (SSA) UV-Vis Spectrophotometry. The results showed m...

Aqueous extract of Diospyros mespiliformis leaves and stem bark in Nangere Local Government area Yobe State were analyzed for its elemental photochemical constituents. The Elemental analysis which was carried out with Atomic Absorption Spectrophotometer (AAS) showed that the plant contains calcium [Ca], manganese [Mn], magnesium [Mg], lead [Pb], copper [Cu] Zinc [Zn] moderate quantity while cad...

OBJECTIVES To study the effect of bis (tributyl tin) oxide (TBTO) on permeability of the blood-brain barrier. METHODS Electron microscopy and an x ray microanalyser with lanthanum chloride as a tracer were used, and blood tin concentrations were determined with an atomic absorption spectrophotometer. Adult male wistar rats received 0.05 ml/kg body weight of TBTO orally. RESULTS A transient ...

Kalimantan is an island surrounded by tropical rain forests and has hot humid weather because it crossed the equator. The affects human working climate in exchange of air room, for example laboratory. This study objective was to know amount per hour at Samarinda Occupational Safety Health Center. tools used were TESTO 425 anemometer, a digital meter, thermohygrometer, manometer, laptop. chamber...

This research was conducted with a view to determine the risks associated Cu, and Ni through consumption of spices viz; curry leaves, ginger, turmeric, garlic cloves) sold within Kaduna Metropolis. The samples were analyzed for Cu using Atomic Absorption Spectrophotometer (AAS). mean concentrations metals in are leaves: - (0.123 mg/kg); (0.029 mg/kg). Ginger:- (0.063 (0.046 Garlic: (0.064 (0.03...

This study aims to determine the levels of heavy metals (Cd) and (Pb) in shellfishes mangroves at Bima bay. The results showed that bivalves mangrove tissue were analyzed for metal content form lead (Pb), Cadmium using an Atomic Absorption Spectrophotometer. From analysis, it indicates 3 species Shellfish which different results; Blood shells (Anadaragranosa) 0.756 ppm, Hiatula (Hiatula chinens...

Farmers in the village of kedungrejo jombang carrying out their activities some them have a smoking habit where cigarettes there are heavy metal content such as lead (Pb). Lead (Pb) is that toxic to human health. can cause interference and damage kidney function system. The purpose study was determine relationship between metals urine actve passive smokers village. This research used Atomic Abs...

Investigating the optical properties of various chemical compounds using UV–vis spectrophotometers is an essential part education in chemistry. However, commercial are usually treated as “magic black boxes”, where dominant majority elements hidden “under hood”. This often limits understanding mechanisms behind generation spectral curves, which turn may impede ability to understand limitations a...
