Simultaneous Adsorption of Iron and Sulfate Ions with Biopolymers
Bibliographic record
Abstract
In this study, we investigated the simultaneous adsorption of iron and sulfate ions onto a natural biopolymer. Chitosan was used to remove anions and cations from aqueous solutions using adsorption in batch and column experiments. The adsorption process is based on two simultaneous running mechanisms, namely ionic interactions for the oxyanion sulphate and complexation for the heavy metal ion. In this context it is essential that both oppositely charged ions are present in the solution for a high performance adsorption. The adsorption capacities for iron ions on chitosan were very promising with a maximum adsorption capacity of 140 mg/g (for the batch experiments). The maximum adsorption capacity obtained for sulfate ions was 210 mg/g. The column adsorption data pointed out that the rate of separation is 100 % for iron ions and 83 % for sulfate ions, respectively.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
