The study about the comparison of analytical performance of the determination of Pb metal ions using Atomic Absorption Spectrophotometer in various laboratories in samarinda has been conducted. The validated methods are linearity, detection limits, quanti... see more

The research about validation method of determination of Cd (II) in NPK fertilizer by Flame Atomic Absorption Spectrophotometry at the Quality Control Laboratory, PT. Pupuk Kaltim has been done. Determination of Cd (II) was done by referring to the Indone... see more

In the present work the air/acetylene flame atomic absorption spectrometry was used for bismuth determination in complex oxides. Interference studies were carried out, and interference with vanadium and molybdenum was detected. The method of standard addi... see more

Phytoextraction, the use of hyperaccumulator plant species to scavenge toxic heavy metals from contaminated soils are considered as an emerging technique for cost effective and environment friendly detoxification. The present study was conducted to evalua... see more

Mercury might be liberated from dental amalgam in toxic amounts for humans, which represent a real health risk. This work presents the direct determination in vitro liberated mercury from amalgam submerged in artificial saliva by cold vapor atomic absorpt... see more

A simple, reliable and rapid method for the extraction of ultra-trace copper(II) using nanoporous SBA-15 sorbent modified with a thiocarbo­hyd­razide ligand, and determination by flame atomic absorption spectrometry is presented. The optimum parameters of... see more

Mass attenuation coefficient is a fundamental parameter of radiation interaction, from which the other radiological parameters like half Value Layer [HVL], tenth Value Layer [TVL], total atomic and electronic cross-sections, mass energy absorption coeffic... see more

The physical and chemical environmental impact in a mining area is inevitable, particularly for open pit mining areas. The impact could affect soil and water quality where mining activities, such as land clearing, blasting and hauling, occur. Thus, enviro... see more

The Barito River as the largest and longest river in South Kalimantan has been convicted as the most polluted river on an international level. Where one of the most commonly found compounds is the heavy metal lead (Pb) with a high enough levels that alter... see more
