Different types of voltametric techniques for selective and sensitive detection of heavy metal ions in wastewater system: a review.
Review in RSC advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Heavy metal contamination in wastewater poses serious environmental and health risks, for which highly selective and sensitive detection methods are required. Voltametric techniques, such as DPASV, SWASV, ASV, CV, and DPV, offer simultaneous detection of multiple elements with quick analysis, accuracy and exceptional sensitivity, good selectivity, and least sample requirements. These techniques determine one or more analytes are measured by observing the current with potential. Among them, those that introduce a preconcentration step have been proven to be powerful electroanalytical techniques for detecting trace metals such as SWASV and DPASV. The outcome of experimental parameters, supporting electrolytes, and working electrodes and their impact on analytical performance are key focuses of this review. Numerous studies have explored voltammetric techniques for detecting heavy metals; however, a thorough comparison of their experimental parameters and analytical performance is uncommon. Operational conditions such as preconcentration voltage, deposition time, scan rate, pH, pulse amplitude, and supporting electrolyte play a crucial role in the magnification of the sensitivity and selectivity of the method. The optimal operational conditions were found to significantly improve the efficiency and analytical performance of the methods. Among the voltammetric techniques, SWASV offers enhanced sensitivity and reduced background noise, making it suitable for trace analysis. Results indicate that SWASV exhibits the lowest LOD in the ng L
