From: Fabrication of novel vildagliptin loaded ZnO nanoparticles for anti diabetic activity
No | Equation | Parameter limits |
|---|---|---|
01 | Vildagliptin adsorbed amount qe = (C0 − Ce)V/M | qe: The adsorbed content of Vildagliptin (mg/g) C0: Initial contents of Vildagliptin (mg/L) Ce: Equilibrium content of Vildagliptin (mg/L) V: Volume of the Vildagliptin (mL) M: Mass of ZnO NPs (mg) |
02 | Vilda Adsorption Percentage P (%) = (C0 − Ce)/C0 × 100 | |
03 | Langmuir Ce/qe = (1/qLKL) + (1/qL)Ce RL = 1/(1 + KLCmax) | qL: “monolayer adsorption capacity” ZnO NPs (mg/g) KL: “Langmuir energy of adsorption constant” (L/mg) RL: sensitive equilibrium parameter or separation factor Cmax: “Highest initial drug content” in the solution (mg/L) |
04 | Freundlich log qe = log KF + intensity (1/n) log Ce | KF: “Freundlich adsorption capacity” ZnO NPs (mg/g) n: “Freundlich constant” characteristics of the system, indicating the intensity of adsorption |
