Background: In the previous study, investigators have synthesized acrylamide grafted and carboxymethylated derivatives of neem gum and evaluated their potential in the formulation of nanoparticles. In continuation of previous work, authors have evaluated neem gum polysaccharide (NGP), acrylamide grafted neem gum polysaccharide (NGP-g-Am) and carboxymethylated neem gum polysaccharide (CMNGP) as binding agent in the tablet dosage form. Methods: Diclofenac sodium was used as a model drug while microcrystalline cellulose and talc were used as excipient in the preparation of granules employing wet granulation technique. NGP, NGP-g-Am and CMNGP were utilized as binding agent in the preparation of granules. Prepared granules were characterized for various pre-compression and post-compression parameters. Results and Discussion: Binding agents were used in the concentration of 4-24%w/w. NGP incorporated granules showed more bulk density and lower values of tapped density, Carr’s index, bulkiness, Hausner’s ratio and angle of repose as compared to NGP-g-Am consisting granules. NGP-g-Am consisting tablets showed more hardness and zero friability as compared to NGP based tablets. Drug content was found lower for the tablets having grafted polymer in place of NGP. CMNGP were also utilized to prepare granules but granules were not be able to compress keeping all the compacting parameters same as used in the case of NGP and NGP-g-Am consisting granules. NGP and NGP-g-Am were able to sustain drug release up to 6 and 8 h, respectively. Conclusion: It can be concluded that NGP-g-Am induces better properties when used as a binder in the tablet formulation than native polymer, while CMNGP cannot be utilized as a binding agent in the preparation of a tablet.

Radioactive Waste Immobilization

Magnesium oxide is a necessary binding agent for the synthesis of a magnesium potassium phosphate (MPP) matrix based on MgKPO4 × 6H2O, which is promising for the solidification of radioactive waste (RW) on an industrial scale. The performed research is devoted to finding a cost-effective approach to the synthesis of MPP matrix by using MgO with an optimal ratio of the quality of the binding agent and the cost of its production. A method for obtaining MgO from the widely available natural mineral serpentinite was proposed. The phase composition, particle morphology, and granulometric composition of MgO were studied. It was found that the obtained MgO sample, in addition to the target periclase phase, also contains impurities of brucite and hydromagnesite; however, after calcining at 1300 °C for 3 h, MgO transforms into a monophase state with a periclase structure with an average crystallite size of 62 nm. The aggregate size of the calcined MgO powder in an aqueous medium was about 55 μm (about 30 μm after ultrasonic dispersion), and the specific surface area was 5.4 m2/g. This powder was used to prepare samples of the MPP matrix, the compressive strength of which was about 6 MPa. The high hydrolytic stability of the MPP matrix was shown: the differential leaching rate of magnesium, potassium, and phosphorus from the sample on the 91st day of its contact with water does not exceed 1.6 × 10−5, 4.7 × 10−4 и 8.9 × 10−5 g/(cm2·day), respectively. Thus, it was confirmed that the obtained MPP matrix possesses the necessary quality indicators for RW immobilization.

Coconut husk is considered waste and its fibers can be used as a source of natural dyes for textiles. The objective of this research is to obtain natural dyes from old coconut (Cocos nucifera) husk waste fibers through the extraction process. Brown color was produced in the liquid-liquid extraction method. The brown color natural dyes were then used to dye cotton cloth. Three different binding agents were used during the fixation process, i.e. tunjung, naphtol salt, and alum. The coloring results of the natural dye on the cotton cloth were as follow: with alum binding agent the resulting color was light brown (cream), whereas tunjung binding agent produced a greenish brown color, and using napthol salt binding agent produced yellow color. The colored cotton cloths were tested for their color fastness properties against rubbing, soap washing, and sunlight exposure. The measurement scale used was grey scales, which was used to evaluate the color change (color fading) and color staining (color transfer) during color fastness testing. In general, based on the results, the colored cotton cloth using alum as binding agent showed better color fastness properties against rubbing, soap washing, and sunlight exposure compared to the ones using tunjung and naphtol salt binding agents.

The use of wastes for developing of new materials is a sustainable approach. In current study filter media produced from industrial waste was tested for an ability to decrease high concentration of zinc in standard solution and industrial wastewater. The geopolymer production requires mixing of post-industrial waste with naturally occurred aluminosilicate materials by using binding agent at the ambient or slightly increased temperature in order to produce a long lasting eco-friendly cementitious material. The tested media decreased concentration of zinc in standard solution from 72,9 to 19,6 mg/L in 30 min showing similar performance as commercially available zeolite material. In experiments with wastewater the adsorption of Zn by AAM was much lower, which can be explained by the fact that wastewater contained generous amounts of different metal ions, organic substances and oils. Despite complex composition of wastewater AAM was able to immobilize at minimum 22 mg/L (32%) Zn from the solution.
