Abstract

In this study, membranes made from chitosan, a natural polymer derived from shrimp shells, were investigated for their ability to remove toxic methyl orange (MO) dye from water. The membranes were characterized using infrared spectroscopy, and the maximum absorption wavelength of MO dye was determined via UV-Visible spectrophotometry. Solutions of varying MO concentrations were passed through the chitosan membranes, and their absorbance was measured before and after filtration. Results showed high removal rates ranging from 85% to 95%, with the highest efficiency observed at 20 ppm MO concentration. This research highlights the potential of chitosan membranes as effective and sustainable solutions for water purification, addressing a crucial environmental and health concern posed by toxic dye pollution. Highlights: High removal rates: Chitosan membranes remove dye efficiently (85%-95%). Eco-friendly: Derived from shrimp shells, chitosan offers sustainable water purification. Advanced analysis: Infrared spectroscopy and UV-Visible spectrophotometry characterize membrane properties. Keywords: Chitosan membranes, Water pollution, Methyl orange dye, Removal efficiency, Environmental sustainability

Abstract

The transition to renewable energy sources necessitates novel solutions for decentralized energy management, secure transactions, and transparent regulatory compliance. This paper presents the design and evaluation of a blockchain-based system addressing these challenges through peer-to-peer (P2P) energy trading, dynamic smart grid coordination, and automated Renewable Energy Certificate (REC) lifecycle management. Employing a hybrid methodology that combined qualitative stakeholder interviews with a six-month quantitative simulation of 50 prosumers, our Ethereum Proof-of-Stake (PoS) platform was assessed for efficiency, latency, and stability. The results indicate superior performance over traditional models, revealing significant gains in energy transfer efficiency, marked reductions in transaction latency under various network loads, near-elimination of REC fraud, and enhanced grid frequency stability. This study empirically confirms that decentralized architectures can augment or replace centralized utility models, establishing blockchain as a viable infrastructure for future smart grids and informing policy decisions needed to create a more resilient and equitable energy market for energy efficiency.
