Adsorption optimization of acyclovir on prepared activated carbon
Bibliographic record
Abstract
Canadian pine cones (pine cone type I and pine cone type II) and deoiled canola meal were utilized as precursors for preparation of powdered activated carbons (PACs) using thermo‐chemical process. Physicochemical properties of the biomass and obtained adsorbents were evaluated. Prepared PACs were investigated for the adsorptive removal of acyclovir (ACV) from aqueous solutions. Pine cone type I PAC was found to have well developed pores and surface area. It was found to be suitable for removal of ACV from aqueous solution. Response surface methodology was used for the optimization of ACV adsorption on PAC prepared from pine cone type I and the development of predictive model. A second‐order polynomial equation fitted data well which indicated that the process variables such as temperature, pH and especially adsorbent dose had large impact on the ACV adsorption process. The optimum conditions for ACV removal were found to be 39 °C, pH 8 and 2 g/L of pine cone type I PAC dose. At these conditions, the removal of ACV was 90.3 %, which was close to the maximum predicted value of 92.5 %.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
