摘要： Potable drinking water is plagued with widespread arsenic contamination, particularly in developing communities. Ferric ions were introduced to interact with arsenate based on the strong affinity of arsenate for ferric hydroxides, followed by mucilage addition. The mucilage coagulated and flocculated the ferric-arsenate complex and formed visible flocs that settled at the bottom of the tubes. The system showed 75-96% arsenate removal in 1 hour, while longer retention times showed 100% removal. The role of the mucilage was demonstrated by untreated solutions showing no concentration difference and remaining stable for more than 15 days. This mucilage-based technology has the potential to be a relatively inexpensive, environmentally sustainable alternative to synthetic polymer flocculants for removing arsenic from drinking water.

摘要： The group of inventions relates to the field of organic chemistry and can be used for cleaning water, industrial and domestic waste water or waste water sediment, and for the containment and recovery of petroleum and petroleum product spills in large bodies of water, rivers, lakes and seas. In the claimed group of inventions, aqueous solutions of polysaccharide microgels, having a molecular mass of 20000-200000 daltons and a particle size of 50-600 nm, are used as a substance for cleaning water of petroleum and petroleum products. Moreover, low concentrations of polysaccharide microgels in water, ranging from 0.1 to 20 g/l, are used. Said solutions are used as a surface modifier for a filter used in separating water-oil emulsions, as a sorbent for the containment and recovery of oil spills in an aqueous medium, and also as a coagulant for the cleaning of water polluted by petroleum and petroleum products. The technical result is in making it possible to recover a commercial product, recovered during the process of cleaning water of petroleum or petroleum products, and to recover the starting substance for the reuse thereof, while simultaneously simplifying the slurry utilization process.

摘要： An object of the present invention is to provide a dispersant for treatment of water. The dispersant is used in a membrane separation process of water containing an organic compound having a phenolic hydroxy group and prevents a reduction in amount of the water permeating a separation membrane, which is caused by deposition of the organic compound onto the surface of the separation membrane. Provided are a dispersant for treatment of water containing an organic compound having a phenolic hydroxy group wherein the dispersant contains a polymer compound having a carbonyl group and a structure including a nitrogen atom bonded to a carbonyl carbon atom; and a method for treatment of water containing an organic compound having a phenolic hydroxy group, wherein the method includes adding the dispersant to the water.
