Preparation of Porous Chitosan Microsphere Absorbent and Research on Its Absorption Ability for Cu2+ and Zn2+
Bibliographic record
Abstract
An amino chitosan absorbent has been prepared with monoethylamine, chitosan, catalyst, cross-linking agent,hydroxylpropyl chlorination agent and amination agent. This paper discusses the effect of monoethylamine modificationon the amino content in chitosan absorbent, as well as its effect on the absorption capacity of absorbent for Cu2+ andZn2+; and investigates the absorption kinetics of chitosan and amino chitosan for Cu2+ and Zn2+. The results indicate thatthe amino content of modified porous microspheric chitosan is higher than that of chitosan; its absorption capacity forCu2+ and Zn2+ increases with the rise of temperature and changes with pH, and there is no obvious difference inabsorption capacity of Zn2+ between chitosan and modified chitosan.

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.
