Experimental dataset supporting “Impact of Aqueous Chemistry on the Electrokinetic Stability and Hydrodynamic Diameter of Ozone Nanobubbles”

Description

This dataset supports the manuscript "Impact of Aqueous Chemistry on the Electrokinetic Stability and Hydrodynamic Diameter of Ozone Nanobubbles". It contains curated and source data derived from ozone nanobubble characterization experiments performed using two analytical platforms: Nanotrac Wave II (Microtrac MRB) and Zetasizer Nano Series ZS90 (Malvern Panalytical). The evaluated aqueous media were distilled water, softened water, and Atoyac River water. The deposited files include curated spreadsheets containing the numerical data used to construct the manuscript tables, appendix tables, and DLS plot-based appendices, together with raw or near-original Nanotrac export files corresponding to individual sample analyses. For the Zetasizer measurements, no native instrument raw files were provided to the authors because these analyses were obtained through a contracted characterization service; the spreadsheet exports available from that service constitute the closest available source records for those measurements. The repository package is intended to provide transparent access to the numerical basis of the study in a reusable format independent of manuscript layout. File organization, abbreviations, variable conventions, and the relationship between the deposited data and the manuscript are described in the accompanying README document.

Steps to reproduce

Ozone nanobubbles were generated in three aqueous media: distilled water, softened water, and Atoyac River water. The generation system consisted of a 40 L recirculation tank, a centrifugal pump operating at 27 L min⁻¹, a KRAN K25 nanobubble generator, and a TOG-08 ozone generator supplied with oxygen. The gas flow rate was maintained at 0.8 L min⁻¹, corresponding to a nominal gas-liquid ratio of approximately 3% under atmospheric reference conditions. Samples were collected at the specified contact times and transported to the analytical laboratory within 15–20 min under ambient conditions. Nanotrac Wave II measurements were performed as time-resolved analyses at the indicated post-generation times. Zetasizer Nano ZS90 measurements were performed as complementary follow-up analyses for selected softened-water and river-water conditions. The curated spreadsheets contain the processed ELS/DLS outputs used for interpretation, while the raw Nanotrac exports preserve the original instrument-reported values. The README file explains file organization, variable definitions, retained instrument saturation values, and interpretation notes required to contextualize the dataset.
