Alginate-Based Sustainable Green Composites of Polymer and Reusable Birm for Mitigation of Malachite Green Dye: Characterization and Application for Water Decontamination

Environmental sustainability appraisal of adsorption for exclusion the malachite green toxic dye was center attention in this work. The influenced goals were to analyze consequences novel composites fabricated by sodium alginate with guar gum and birm (SA@GG@B composites) ion gelation. This work not only explains feasibility sorbent its application removal stuff but also proclaimed various effects different parameters affecting efficiency. Adsorption processes carried out batch process. composite characterized SEM, which revealed that irregular surface has pores present high adsorption, FTIR (for functional groups detection) reveals presence –OH group provides attachment sites dye, BET (surface analysis) a area 5.01 m2/g shows it wide greater performed on synthetic varying like contact time, concentration sorbate, pH. Maximum achieved (92.7%) at 100 ppm initial concentration, 120 min interaction pH 9. isotherms (Freundlich, Langmuir, Dubnin, Elvoich isotherm) applied evaluated phenomenon nature adsorption. Freundlich capacity KF (9.45) effective proposed adsorbent. kinetics models show better pseudo-second-order reaction. Effective synthesized their importance industrial water purification from hazardous dyes.
