The current work used a batch study to investigate the efficiency of Ulva lactuca carbon for lead adsorption from aqueous solution. For the optimization study, the effects of several parameters such as pH, Adsorbent dosage, effective contact time, and initial concentration on lead removal were also considered. pH 3 was observed to be the most beneficial. The Langmuir isotherm, which represents mono-layer adsorption, yielded a maximum lead absorption of 3.49 mg/g. SEM was used to examine surface adsorption behavior, and FTIR was used to detect probable functional groups involved in the bio-adsorption experiment. This study shows that biochar made from the marine algae Ulva lactuca is effective for waste water treatment.

The goal of this investigation was to check the feasibility of Ulva lactuca carbon could be used to adsorb acid yellow 19 dyes from an aqueous solution. A series of studies were carried out to determine the best conditions for acid dye adsorption. 90 percent colour removal was achieved when pH 3, 1 gm dose, 100 mg/L dye concentration were used for dye adsorption. During the analysis, it was discovered that as the carbon dose was raised, the dye elimination rate rose. The main objective of this study is to reduce solid waste disposal while also addressing the issue of seaweed and developing an effective plan
