Abstract

The requirement to discover low-cost and high-efficiency adsorbents material for the heavy metal removal of industrial effluents has been growing attention for many environmental researchers. Natural materials are being studied intensively as adsorbent materials because of their abundant source, low-cost processing, and relatively high adsorption efficiency. This study investigates the tofu dregs as adsorbents material to remove chrome metal, the main element in tannery liquid waste. Analysis of experimental data from adsorption processes is crucial to understand and predict removal mechanisms, efficiency, or required adsorbent mass under given initial conditions. Langmuir and Freundlich's adsorption isotherms were applied to the experimental data to determine their intrinsic parameters. The intrinsic parameters of Langmuir and Freundlich adsorption isotherms can subsequently be used to analyze the adsorption mechanism. This was achieved by combining the isotherms equation with mass conservation of solute before and after adsorption

Abstract

Ultrasound-assisted Extraction (UAE) is one of the potential ways to increase the yield and quality of bioactive compounds. Besides, the UAE is environmentally friendly since the solvent used is a lesser, non-toxic solvent, time-saving, and operated at a lower temperature, leading to the increase of mass transfer. Ultrasound is one of the wave sounds that have a frequency range that is above the range that can be heard by humans (20 MHz). This wave could cause the breakdown in plant tissue via cavitation, the forming of vacuum bubbles from a wave sound on a liquid material. The breakdown of plant tissue leads to the release of bioactive compounds. These compounds, then, are dissolved in the solvent. The types of bioactive compounds that can be extracted using ultrasound waves are polyphenols, carotenoids, aromatic compounds, and polysaccharides from plant matrix. The UAE method is affected by the temperature, frequency, and amplitude of the wave, density, types of solvent, extraction time, and plant matrix. This article would review the principles of UAE method, cavitation, the characteristic of tissue exposed to ultrasound, and the devices used during the extraction.

Abstract

This review article focused on the investigation of UV radiation's interactions with PET plastic in photografting. The photografting technique involved exposing PET packaging to UV radiation before utilizing it to package food. Surface graft polymerization was frequently carried out using UV light, frequently in the presence of a photoinitiator or photosensitizer. The results were intriguing since UV irradiation caused by PET and UV interaction will result in a hydrophilic nature in order for surface photography to create photografting and PET film with antibacterial properties. Therefore, many other industries, including the food industry, use photografting in this way.
