The findings illustrate that, among the five clay types studied, the kerolitic montmorillonite is particularly effective in removing tetracycline from water, achieving levels of approximately 100 mg/g. This effectiveness is remarkably consistent across a range of pH levels (both acidic and basic), temperatures (4–60 °C), and even flow rates when employing the honeycomb design (50–2800 mL/min).
