Static removal of cadmium from aqueous and nonaqueous matrices by application of layer-by-layer chemical deposition technique

Implementation of layer-by-layer chemical deposition technique for static removal of magnesium from various matrices

“…In addition, the static removal of metal ions from their matrices as expressed in the form of percentage extraction or surface coverage is heavily dependent on the number of successive reaction dipping cycles [31]. However, a single dipping cycle is mainly based on the immersion of glass substrate into 8HQ as the ligand solution for the deposition of first layer of 8HQ-molecules This step is followed by immersion into the metal ion solution for deposition of Mg(II) ion and subsequent formation of the first layer of Mg(II)-8-hydroxyquinoplate complex.…”

“…In this method, a glass micro-slide of the dimensions 76.0 mm, 25.0 mm and 1 mm was used as the solid substrate. The glass micro-slides were cleaned as previously reported [31,32] by ultrasonication in chromic acid, detergent solution, double distilled water and dried in an oven.…”

“…This methodology was recently used and successfully implemented for static removal of cadmium from aqueous and non aqueous matrices. The process of static removal of cadmium was monitored and optimized by several important controlling factors leading to excellent recovery values of Cd(II) from various aqueous and nonaqueous samples [31].…”

Adsorptive removal of Mn(II)–Mn(VII) from various aqueous and nonaqueous solutions by using layer-by-layer chemical deposition technique

“…In addition, LbL has been also examined and successfully used for synthesis of several important classes of nano-compounds and nano-materials via thin film formation [21][22][23][24][25][26][27][28]. The description of this technique for thin film formation of various nano-materials was previously reported [22][23][24] and recently discussed in static removal of some heavy metal ions from various matrices [19,20]. Generally, static removal of heavy metal by using LbL chemical deposition is performed via direct deposition of alternating layers of oppositely charged materials.…”

“…One real promising approach which has recently emerged, employed and implemented as an efficient technique for solid phase extraction and static removal of heavy metals such as cadmium and magnesium from aqueous and nonaqueous solutions is known as layer-by-layer (LbL) chemical deposition technique [19,20]. In addition, LbL has been also examined and successfully used for synthesis of several important classes of nano-compounds and nano-materials via thin film formation [21][22][23][24][25][26][27][28].…”
