TL;DR: In this paper, the sorption process of tribenuron methyl, a sulfonylurea herbicide, on the hydroxyapatitic and fluoroapatite minerals has been studied using batch method.
Abstract: The sorption process of tribenuron‐methyl, which is a sulfonylurea herbicide, on the hydroxyapatite and fluoroapatite minerals has been studied using batch method. Desorption of this pesticide from the solid is also investigated using column method. From UV‐visible data, it was found that the pesticide was more removed with the hydroxyapatite than with fluoroapatite samples. Using 1 g of HAp and of FAp, the maximum removed amount of tribenuron methyl from a solution of 2.5 × 10−4mol/L was respectively 1.65 × 10−4mol/L and 0.53 × 10−4mol/L. This is related to the specific surface area and to the solubility of minerals.

TL;DR: In this article, synthetic hydroxyapatites containing metal oxides were precipitated from solution and characterized using both structural and chemical techniques, and the electrical conductivity of the resulting frequency-dependent conductivity displays a behavior characteristic of structurally distorted solid electrolytes.

TL;DR: The influence of temperature, ripening time and solvent nature on the crystal growth of apatite was investigated in this article, where a dissolution-precipitation method was used for the synthesis of nanoporous apatites.
