1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundIron (Fe) contamination in groundwater is a gradual yet significant concern driven by industrial, urban, and agricultural activities, resulting in undesirable organoleptic effects in drinking water. Surface immobilization of bacterial strains onto biochar offers a promising strategy for enhancing adsorption-based remediation. PURPOSE: This study investigates the adsorption behaviour of Fe(II) ions using a bacterial-biochar immobilized adsorbent derived from rice husk and Bacillus subtilis, isolated from iron-rich soil samples near handpumps located in Haridwar, Uttarakhand, India. The goal was to evaluate the impact on the adsorption capacity for Fe (II) through various sorption and kinetic models, along with material modified properties.

methodsRice husk biochar was immobilized with Bacillus subtilis and characterized using SEM, BET surface area analysis, and FTIR spectroscopy. Batch adsorption experiments were conducted across Fe(II) concentrations of 10-40 mg/L. Three Sorption kinetics were modeled for fitting the data and similarly three Isotherm behaviors were assessed, supported by regression analyses.

resultsThe bacterial-biochar immobilized adsorbent achieved 79.3% Fe(II) removal, outperforming pristine biochar. BET surface areas of 67.76 and 91.84 m

conclusionsSurface immobilization of Bacillus subtilis onto rice husk biochar significantly enhances Fe(II) adsorption. These findings highlight the potential of bacterial-biochar immobilized adsorbent as a basis for valorization of the green biotechnology usage in groundwater remediation applications.
