Distribution of Trace Metals in Street Dusts and Tree Leaves and Their Source Identification in a Mid-Populated Anatolian City.

Sivas is a central Anatolian city in Turkey with mid-population. Due to its geographical structure high air pollution episodes can be observed in the atmosphere of Sivas. A study with city wide sampling campaign can help to identify the possible sources.

Biosorption of Ga-67 radionuclides from aqueous solutions onto waste pomace of an olive oil factory.

The aim of this research was to test the removal of Ga-67 radionuclides from aqueous solutions by biosorption onto waste pomace of an olive oil factory (WPOOF). Batch adsorption studies were performed in order to investigate the temperature, the initial pH of the solution, the stirring speed, the biosorbent dose, and the nominal particle size of the biosorbent in the experimental work. The most effective parameter was found to be the initial pH.

An environmentally friendly process; adsorption of radionuclide Tl-201 on fibrous waste tea.

This work presents an investigation of the adsorption of the radionuclide of Tl-201 from waste water on the fibrous tea factory waste. The experimental parameters were chosen as temperature, pH, stirring speed, adsorbent dose and nominal particle size in the ranges of 10.0-40.

Biosorption of Cu(II) ions onto the litter of natural trembling poplar forest.

The litter of natural trembling poplar (Populus tremula) forest (LNTPF) was used for the biosorption of Cu(II) ions in a batch adsorption experiments. The sorption capacity of LNTPF was investigated as a function of pH, particle size, agitating speed, initial Cu(II) concentration, adsorbent concentration and temperature. The efficiency of copper uptake by the used LNTPF increases with a rise of solution pH, adsorbent concentration, agitating speed, temperature, and with a decline of particle size and initial Cu(II) concentration.
