Maize seedlings pretreated with 0.25 mM NTB and exposed to 100 µM CdCl2 showed a 69% increase in Cd accumulation. NTB reduced oxidative stress, lowering TBARS and H2O2 levels by 37% and 34%, respectively. Proline accumulation rose by only 12%, and RWC increased by 9%, indicating improved stress tolerance. Antioxidant enzyme responses shifted: SOD activity declined by 71%, while CAT, APX, and GPX decreased by 24%, 19%, and 37%. NTB also elevated antioxidants, including gallic acid (61%), epicatechin (71%), vanillic acid (42%), and rosmarinic acid (64%). Total chlorophyll increased by 68%, and gas exchange parameters improved: Pn by 70%, Tr by 46%, gs by 14%, and Ci by 72%.

S. portulacastrum was cultivated in vermiculite and was watered twice a week with various concentrations of NaCl alone or combined with two concentrations (M1 and M2) of a multi-metal mix containing Ni, Co, Cr, and Mn. The results showed that shoot growth was at its maximum in the presence of 0 and 200 mM NaCl. At this last salt concentration, the M1 metal level in the substrate had no significant effect, but M2 decreased plant growth drastically. However, the total metal accumulation in shoots and roots was the highest under M2 multi-metal exposure. S. portulacastrum accumulated relatively high levels of metals in roots under varying salinity conditions.

The adsorption behavior of the biosorbent was examined by varying several parameters, such as pH, dye concentration, adsorbent amount, thermodynamics, and equilibrium time. Adsorption isotherms and kinetic models were also fitted. The maximum adsorption capacity of CV on ACG was found to be 111.11 mg/g achieved at 35 °C or 308.15 K. The calculated thermodynamic parameters, such as ΔH and ΔS for CV uptake on the adsorbent surface, come out to be 22.397 kJ/mol and -100.25 J/mol/K, respectively. The positive enthalpy change, confirms the endothermic nature of the adsorption process. The negative values of ΔG confirmed the spontaneous nature of the adsorption process. The recyclability of the adsorbent is also good after four cycles of regeneration, and the adsorbent has ∼80% removal with the real waste water sample.
