Lignocellulosic Biomass Waste Adsorbent for Removal of Dye from Aqueous Solution
Bibliographic record
Abstract
Date Palm Tree Fiber (DPTF) is a renewable raw material which is considered a biomass waste excess of date farms and manufactures. This biomass was successfully utilized as solid phase extractor (SPE) for removal of methylene Blue dye (MB) from polluted water. The chemical composition and the surface morphology of the SPE was critically assigned based on FT-IR, and FE-SEM. In batch separation mode, the impact of several analytical parameters e.g. contact time, weight of biomass, solution pH and initial concentration on the MB dye uptake from aqueous media by DPTF solid adsorbent was critically studied. At the optimized parameters, good adsorption capacity (qe,exp =9.153 mg/g) at pH 6 was achieved. The data of MB uptake were subjected to Langmuir and Freundlich to assign the most probable retention mechanism. The adsorption fitted well with Langmuir isotherm models qm 648 mg/g. The data were fitted well with pseudo- second order model as supported from the qe,cal (9.225 mg/g) value. Excellent extraction (99%) of MB dye was achieved from the environmental water samples. The DPTF solid sorbent is a non-toxic and renewable raw material of lignocellulosic biomass has a potential to uptake MB dye from wastewater.

How this classification was reachedexpand
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.
