Starch–metal complexes and metal compounds

Abstract

Recently, metal derivatives of starch evoked considerable interest. Such metal derivatives can take a form of starch compounds bearing metal atoms and metal carrying moieties either covalently bound or complexed. Starch metal complexes may have a character of either Werner, inclusion, sorption or capillary complexes. In this publication, preparation, structure, properties and numerous current and potential applications of those compounds as well as benefits resulting from the application and formation of the complexes are presented. © 2017 Society of Chemical Industry.

Swelling and Shrinking Behavior of Modified Starch Biopolymer with Iron Oxide

“…The starch contains plenty of CH 2 OH on starch chains. The Fe(III) cations have also make a complex with OH group of the starch which shows the proposed crosslinking of oxidized starch with Fe(III), [ 61–65 ] as shown in Figure 10a,b. The starch–iron oxide complex in Figure 10c could act as a reinforcing agent to increase the mechanical properties of starch‐based materials.…”

Starch based nanocomposites as sensors for heavy metals – detection of Cu2+ and Pb2+ ions

“…This dependence could be explained by the presence of both static and dynamic quenching (Koneswaran and Narayanaswamy, 2009). Starch used in the synthesis is a well known heavy metal chelating agent, which forms complexes with Cu 2 + and Pb 2+ (Staroszczyk et al, 2017). The composite formed elastic foils emitting blue light when excited with UV (365 nm) radiation (Fig.…”

Biodegradable Binary and Ternary Complexes from Renewable Raw Materials

“…Domestic polysaccharide resources can be used without deep processing, adapting them to different purposes through physical, physicochemical, chemical and enzymatic modification. Examples of such applications may be adhesives; microcapsules; absorbents; and additives for the production of pulp, paper, biodegradable materials and plasticizers, which are important in the new generation of ceramics [ 133 , 134 , 135 , 136 , 137 ].…”

“…Systems have properties that enable the capture of relatively large volumes of water, creating a “clathrates”. These properties allow them to be used, inter alia, as collector metal ion binding substances, able to separate heavy metals from soil, as stabilizing substances (organic fertilizer) on embankments and on the waterfront of rivers, and as components of drilling fluids, causing, in addition to the lifting of excavated material, the improvement of lubrication holes and drill levelling disorders [ 137 , 138 ].…”
