The study targets two objectives: green synthesis of silver nanoparticles (AgNPs) using marine diatoms Chaetoceros sp. and Thalassiosira sp., and immobilization of diatoms in Ca-alginate hydrogel beads via gelation. Thalassiosira sp.-mediated AgNPs remove phosphate and nitrate at 74% and 65%, while reducing chemical oxygen demand (COD) by Chaetoceros-mediated AgNPs to 73%. Encapsulation further improves removal rates: 91% phosphate, 64% nitrate, and 78% COD, supported by strong biochemical profiles and potential for scalable treatment.","cbCaijC4VbZfYyS7","https://ap.wps.com/l/cbCaijC4VbZfYyS7","pdf",733773,1,12,"English","# Abstract\n# Introduction","[{\"question\":\"What two goals does the study pursue for municipal wastewater remediation?\",\"answer\":\"It performs green synthesis of silver nanoparticles using marine diatoms and encapsulates diatoms in Ca-alginate hydrogel beads to evaluate nutrient bioremediation from wastewater.\"},{\"question\":\"How effective were diatom-mediated AgNPs for removing phosphate, nitrate, and COD?\",\"answer\":\"Thalassiosira sp.-mediated AgNPs removed phosphate and nitrate at 74% and 65%, respectively.
