What is the process involved in extracting iodine from the ashes of macroalgae?
Best insight from top research papers
The process involved in extracting iodine from the ashes of macroalgae involves several steps. First, the macroalgae are decocted at high pressure to improve extraction efficiency and reduce energy consumption . Then, the decocted algae are subjected to reflux extraction through decocting water to further improve extraction efficiency . After this, a carbon tetrachloride extraction method is used to extract coarse iodine, which is quick and efficient with low energy consumption . Another method involves mashing, vacuolation, decocting, heavy metal adsorption, heavy metal sedimentation, filtration, and separation on the macroalgae. Alcohol is added to assist dissolution, sodium alginate is added to adsorb heavy metal matters, and chitosan is added to generate sedimentation . Additionally, a method involves kelp immersion, purification, acidification oxidation, resin adsorption, reduction desorption, and iodine oxidation precipitation. This method effectively purifies the kelp immersion liquid and improves the iodine yield .

How effective is macroalgae in removing contaminants from water compared to other methods?4 answersMacrophytes, such as seaweeds like Sargassum, exhibit promising potential in removing contaminants from water. Studies have shown that Sargassum can not only absorb iron pollutants but also metabolize them into non-toxic forms, making it a cost-effective and efficient alternative to traditional methods of pollutant removal. Additionally, microalgae, like Chlamydomonas pertusa, Dactylococcopsis raphioides, and Chlorococcum humicolo, have been found effective in reducing various pollutants in water, including Total Dissolved Solids, Total Suspended Solids, free ammonia, calcium, sodium, nitrate, and phosphate, showcasing their potential in phycoremediation. These biological methods offer eco-friendly and sustainable solutions for water remediation, with microalgae showing particular promise due to their ability to remediate emerging pollutants at low costs.

Can iodine be removed in seaweed?5 answersIodine can be removed from seaweed through various processing methods. Washing and related processing steps such as soaking, blanching, and rehydrating are generally effective in reducing the concentration of iodine in seaweed biomass. Steam treatment and warm water treatments using freshwater or seawater have also been found to significantly reduce the iodine content in brown seaweed. Additionally, a treating method using ozone (O_3) has been developed to precipitate and collect iodine from seaweed. Another method involves treating seaweed with a treatment solution containing seawater, starch, and an oxidizing agent, which extracts iodine from the seaweed. These methods aim to reduce the iodine content in seaweed while maintaining its nutritional and sensory qualities.
What is the process for extracting oil from microalgae using alcohol?5 answersThe process for extracting oil from microalgae using alcohol involves different methods and solvents. One method is the ultrasonic-assisted extraction, where ethanol ultrasound cavitation is used to extract oil from microalgae. Another method is the use of supercritical carbon dioxide entraining ethanol, where microalgae freeze-dry powder is mixed with glass beads and extracted using a supercritical CO2 entrained ethanol fluid. Additionally, the Bligh and Dyer method and the Hara and Radin method use green solvents such as 2-methyltetrahydrofuran (2-MeTHF) and cyclopentyl methyl ether (CPME) to extract lipids from microalgae. Another method involves adding an organic solvent to a high shear mixer, which allows for effective lipid extraction with reduced energy consumption.
What are the different methods of extracting lipids from microalgae?5 answersDifferent methods of extracting lipids from microalgae include mechanical and non-mechanical techniques for cell lysis, as well as classical and innovative approaches for lipid extraction. Mechanical methods involve the use of shear forces, pulse electric forces, waves, and temperature shock to disrupt the cells and release the lipids. Non-mechanical methods include the use of chemicals, osmotic pressure, and biological agents to achieve cell disruption and lipid extraction. Classical methods such as the Bligh and Dyer method and the Folch method have been used for lipid extraction, but they require subsequent separation of lipid families. Innovative approaches, such as 2D fluorescence spectroscopy using Nile Red, have been developed for rapid and accurate quantification of lipids in microalgae. These methods aim to optimize lipid recovery and develop green and effective techniques for lipid extraction from microalgae.
What are the most effective methods for extracting MAAs from algae?5 answersThe most effective methods for extracting mycosporine-like amino acids (MAAs) from algae include successive extraction with water and methanol. This method has been shown to yield the highest amount of MAAs when compared to other tested conditions. Additionally, the content of MAAs in algae can vary depending on environmental conditions and season. Another method involves cell disruption of algae samples to dissolve-out phycobiliprotein, followed by solid-liquid separation to obtain a crude extract liquid. This crude extract liquid can then be mixed with inorganic salts to perform salting out, resulting in the collection of precipitates. These methods have been successfully used for the extraction and analysis of MAAs from various types of algae and marine biota.
