Kinetic analysis of copper ions adsorption on sunflower hulls

Proceedings - 56th International October Conference on Mining and Metallurgy - zbornik radova
This paper presents the kinetic analysis of the adsorption process of copper ions on sunflower hulls. Three theoretical kinetic models were used to analyze the experimental results: the pseudo-first order kinetic model, the pseudo-second order kinetic model and the Elovich kinetic model.

The effect of hull hardness on sunflower germination and susceptibility to Indian meal moth [PDF]

Ratarstvo i povrtarstvo
Sunflower hull hardness significantly affects seed performance in the field, but its effect on seed susceptibility to major seed pests during storage has not yet been assessed. The aim of this research was to determine the effect of sunflower hull hardness (based on a puncture force) on seed germination, and suitability/susceptibility to Indian meal ...

Biochar impacts on carbon dioxide, methane emission, and cadmium accumulation in rice from Cd-contaminated soils; A meta-analysis

Ecotoxicology and Environmental Safety
Climate change and cadmium (Cd) contamination pose severe threats to rice production and food security. Biochar (BC) has emerged as a promising soil amendment for mitigating these challenges. To investigate the BC effects on paddy soil upon GHG emissions,

Statistical modeling of copper ions biosorption onto sunflower hulls

Proceedings - 56th International October Conference on Mining and Metallurgy - zbornik radova
The statistical modeling of the copper ions biosorption onto sunflower hulls is presented in this work. The analysis was conducted using the Response Surface Methodology coupled with the Box-Behnken Design. The software experimental design, consisting of 17 experiments, was applied to optimize the biosorption process.
