| Abstract | ||||
| Chara sp < em>. is a genus of green algae that was selected and dried for the present investigation. The effective functional groups of the algae for infrared adsorption include COOH, OH, C=O, and C-H. Several samples were taken and tested, including negative groups such as CH2, CO3, Cl, Br, and P=O, on the surface of algae weighing 2 grams. These samples were exposed to varying concentrations of lead ions, starting at 0, 5, 10, 20, 40, and 100mg L-1. After the incubation period, the samples were incubated at a temperature of 298K. Using a number of equations, stabilizers were extracted and lead was quantified. The determination values for all the equations were significant, indicating that any of the six equations could be used. The most effective mathematical description of adsorption was provided by the Langmuir equation, which demonstrated a strong correlation between the measured and calculated adsorption values. This equation had the highest coefficient of determination (R2) of 0.71 and the lowest standard error of 0.001, giving it an advantage over the other equations. Data analysis revealed that the highest adsorption capacity (Xm) on both surfaces of the green algae was 0.93 and 58.48mg kg-1, respectively. At the same time, the binding energy (K) on both surfaces was 99.22 and 4.38L mg-1, respectively. These results suggest that algae could be used as a low-cost technology for treating lead-contaminated water and reducing its associated risks. | ||||
