Medicinal plants form the basis of sophisticated traditional medicine system that has been in existence for thousands of years, which continue to provide mankind with new remedies. Herbal plants are consumed worldwide for the treatment of several diseases and such plants are the important source of raw material for pharmaceutical industries. As a micronutrient, heavy metal plays an essential ro...

Bogra city is highly susceptible to environmental pollution due to over population, rapid industrialization and urbanization during the last decades. A study was conducted to determine heavy metals (Cu, Zn, Pb, Cr, Cd and Ni) pollution level and physicochemical properties in the soils of Bogra city. The concentrations of heavy metals in 14 soil samples were determined by using an Atomic Absorpt...

Tricalcium Phosphate Anhydrous Powder typically contains 300 to 400 mg/Kg (w/w) of aluminum. This level can be determined utilizing AAS and standard based on known standards. In this study, we have determined the amount of aluminum metal present in sample of Tricalcium Phosphate Anhydrous Powder using Atomic Absorption Spectrophotometer (AAS). The method has high precision and accuracy. The res...

INTRODUCTION The aim of the present study was to investigate whether the concentration of arsenic (As) released from gray or white mineral trioxide aggregates (MTAs) met the requirement of the International Standards Organization (ISO) for dental cements. METHODS Sample preparations were carried out according to the ISO methods. After centrifugation of dissolved samples, As (III) concentratio...

In this study, the molecule formation mechanisms of strontium mono fluoride used for the determination of fluorine in a high-resolution continuum source atomic absorption spectrophotometer was investigated. To distinguish between the gas-phase and the condensed-phase mechanisms, the analyte (F) and the molecule forming element (Sr) were injected on the solid sampling platform manually, as mixed...

A flame photometric method using atomic fluorescence (AFS) for cadmium (Cd) estimation is described and applied to the measurement of Cd in blood. The AFS system employs a modified, low cost atomic absorption spectrophotometer, with a high intensity Cd light source provided by an electrodeless discharge tube, excited in a thermostatted microwave cavity. The analytical sensitivity of the techniq...

Because of the large quantities of venous blood required, assays of total iron-binding capacity (TIBC) and serum iron are often omitted in diagnostic tests involving small children. As an alternative to the conventional method of assessing TIBC, we developed a micromethod based on flameless atomic absorption spectrophotometry (flameless AAS). Additionally, the standard microproc#{233}dure for d...

The present study deals with effluent analysis of a paper mill using cotton comber and cotton linter as raw material for paper manufacturing process. The effluents generated at different stages were collected. The fibrous sludge samples recovered in different section of mill were also collected. The inorganic parameters i.e. alkalinity, hardness, sulphate, chloride, phosptahe, sodium, potassium...
