This study introduces triethylenetetramine (TETA) as an innovative complexing agent in electroless nickel plating, in comparison to traditional agents such as citric acid, tartaric acid, and lactic acid. Various evaluation methods reveal that TETA dramatically enhances solution stability, coating uniformity, and corrosion resistance. Notably, TETA enables rapid plating at 90°C and maintains an impressive rate of over 10 μm/h at lower temperatures (75°C), outperforming conventional formulations. Additionally, the coating performance at 75°C is superior to that at 90°C, exhibiting enhanced stability and prolonged corrosion resistance under neutral salt spray tests. Wavefunction analysis indicates that the chelation strength between the complexing agents and nickel ions follows the order: triethylenetetramine > citric acid > tartaric acid > lactic acid. Theoretical calculations align with the overall performance of the coatings obtained from formulations using different complexing agents.

Material characterization using FESEM and TEM revealed well-dispersed GQDs on ZIF-8 cubes, confirming composite synthesis. Response surface methodology (RSM) was utilized to examine the effects of adsorbent dosage, initial CR concentration, and contact time on adsorption capacity, providing useful insights into the adsorption process. Specifically, increasing the initial CR concentration and contact time led to an increase in the CR adsorption capacity from 96.5 to 164.9 mg/g and from 176 to 267.4 mg/g, respectively, for definite operating conditions. Additionally, decreasing the adsorbent dose from 100 to 40 mg/L boosted the CR adsorption capacity by about 50 % (i.e., from 164.9 to 246 mg/g). Furthermore, multiple adsorption models were successfully combined using advanced machine learning (ML) models— Extreme Gradient Boosting (XGB), Support Vector Regression (SVR), Random Forest (RF)—and their ensemble combinations (SVR-RF, SVR-XGB, XGB-RF) to predict adsorption performance with high precision. All ensemble combinations yielded higher test R² values and lower prediction errors compared to their corresponding individual base models. Shapley Additive Explanations (SHAP) analysis was applied to unravel the black-box nature of these models, identifying contact time as the most crucial factor, followed by initial CR concentration and adsorbent dosage. The adsorption kinetics followed the Avrami model (R<sup>2</sup> = 0.9999), suggesting a complex mechanism. Additionally, isotherm studies demonstrated exceptional fits to the Langmuir (R<sup>2</sup> = 0.9966) and Redlich-Peterson (R<sup>2</sup> = 0.9973) models, with a maximum Langmuir adsorption capacity of 421.3 mg/g.

OVA was chemically modified with four fatty acids (myristic, palmitic, stearic, and oleic acids) using N-hydroxysuccinimide (NHS) esters.
