INTRODUCTION Recently, there has been a growing stipulate for the growth of nano sized semiconductors than bulk due to their noteworthy electrical and optical properties. Zinc oxide has attracted much interest as a potential nanomaterial due to the inexpensive and n-type semi conductor of wurtzite structure with wide band gap of 3.2-3.3 eV. ZnO have widely been used in various applications such as solar cells, photo catalyst, biosensors, photo luminescent material and antimicrobial activity [1-5]. Several methods were adopted for the production of nanoscale ZnO such as vapour deposition [6], precipitation [7], sonochemical method [8], laser ablation [9], oxidation process [10], solvothermal and hydrothermal methods [11], a polymerization method [12] and sol-gel synthesis [13]. Among these methods, sol-gel technique is inexpensive, simple and produces high purity with large surface area of ZnO nanoparticles. In regulate to prove ZnO nanoparticles from endure impulsive development and aggregation, many scientist have attempted to utilize a variety of organic ligands [14]. Adding organic compounds such as poly(ethylene glycol)

Micro-and nano-sized magnetic adsorbents on the basis of elemental metals, iron oxides, and ferrites, supported by inorganic (carbon, graphene, silica, zeolites) or organic (macromolecules, polysaccharides, polymers, biomolecules) compounds, are reviewed. Main attention is paid to magnetic hydrogels, xerogels, and aerogels due to their high number of environmental and biomedical applications. Role of carbohydrates and polysaccharides (starch, alginic acid, chitosan, etc.) for stabilization of magnetic nanoparticles and use the formed composites for adsorbtion purposes is described. Magnetic adsorbents are mainly used for heavy metals removal, separation, destruction and adsorption of oil, dyes, toxic organic compounds, several biomolecules and drugs, as well as widely in the catalytic processes. These last applications of magnetic adsorbents, in particular ferrites, are emphasized. Their main advantage for these or other possible applications is that the adsorbent or catalyst can be easily removed from reaction media after adsorption or completion of reactions via a simple magnet. Magnetic behavior studies of magnetic adsorbents are also discussed.

“…The 2θangle range selected was 6-84° with a step size of 0.02 for 0.25 s per step. Particle size estimations were evaluated according to Scherrer's equation [5]. Few powder particles of the samples were placed on conductive carbon sticky pads with a spatula and gummed unto aluminum stubs for Scanning Electron Microscopy (SEM) analysis.…”

“…They are often present in small amounts in mgg -1 or ngg -1 range yet pose great concern to the petroleum industry and to the environment due to their ability to accelerate corrosion of distillation towers and turbines, poison catalysts by pore clogging, fissure and deform reactors, pollute the environment, upset natural environmental balances, contaminate food, etc. [4,5]. Demetallization, which has to do with the removal of these metal ions, is therefore a statutory process to enhance efficiency in the oil industry.…”

“…Among the heavy metals found in crude, nickel determination after demetallization is crucial being constituent of catalysts used in refining processes [4]. Some of the techniques employed for demetallization include coking and hydro treatment [6], microwave-chemical method [7] and most recently, the use of metal oxide nanoparticles, Starch Stabilized Magnetic Nanoparticles (SSMNPs) for the removal of nickel from crude oil monitored by UV-Vis spectrophotometry [5]. The UV-V is method reported dissolved 0.2 ml of the filtrate in 10 ml of hexane for analysis.…”

Aluminum oxide nanoparticles (Al 2 O 3 +SDS and Al 2 O 3 ) were synthesized by a simple sol-gel method for demetallization of nickel from crude oil-water mixture in a batch adsorption process for the first time. The samples were dried, calcined at 550°C, cooled and characterized using scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD) techniques. The XRD confirmed that Al 2 O 3 phase were synthesized with more minor impurities of bauxite and silica in Al 2 O 3 without SDS. Particle size estimations were 197 and 183 nm for the Al 2 O 3 with and without SDS, respectively. SEM showed larger rectangular porous crystallites and thinner netlike-vertical platy crystallites for the former and later samples respectively while the EDS confirmed the presence of Al and O in them. The batch adsorption showed that the %Removal (%R) of the adsorption process increase gradually with increase in adsorbent from 0.02 to 0.1 g to a maximum at 86.1% for Al 2 O 3 +SDS but decrease with increase in the adsorbent dosage for Al 2 O 3 with %R maximum of 78% at the least (0.02 g) dosage. On the other hand, at constant adsorbent dosage, %R of 94 and 93% for a 1:3 crude oil-water mixture were obtained for
