The AAc/GO nanocomposite hydrogel was successfully employed as a polymeric Nano sorbent of the removal efficiency of M G dye from the model. The complication of the mechanism of the adsorption system was completely exposed by examining how solution pH affects adsorption, Ionic strength isotherm models, kinetic models, and thermodynamics. The adsorption of the MG dye was greatly dependent on the solution pH. The Freundlich model has been demonstrated to be the most accurate in describing the MG dye sorption, whilst the Langmuir model was shown to be the least accurate. Additionally, these integrated mechanisms fit nicely within the framework of a pseudo-second-order model. Additionally, the contact time at equilibrium short (ten minutes) required to MG removes demonstrates the AAc/GO nanocomposite hydrogel can be considered an efficient and potentially useful adsorbent for MG removal from industrial effluents.

The last decades of this century witnessed a wide interest in three heterogeneous compounds, especially nitrogen atoms, which were represented by triazole rings and their derivatives, whose effects were studied in the widest medical and pharmaceutical journals and as anti-cancer agents and other groups that are characterized by the presence of electronic pairs, which have given greater importance for this reason. In order to increase the effectiveness of any compound, it must include in its composition active groups, donor groups, or electron pairs, and this has been proven by researchers in biochemistry, coordination research, reagent chemistry, reagents, analytical chemistry, estimation of elements and ions in river water and environmental models. Extensive studies have been conducted for the reagents under study to determine their chemical structures through microscopic technical examinations, spectroscopic techniques (Uv-Vis, FT.IR, H.NMR, Mass)–spectra, also Analytical studies like: {Thermal study, TLC–Technique, Scanning Electron Microscopy (FESEM)} and other physico-chemical measurements.

The method was published for determining microgram quantities of benzene 1,3,5-triol (phloroglucinol) in aqueous solution and some bulk samples using an easy, quick, and effective spectrophotometric method. The method uses a diazotization as well as coupling process in basic medium to produce a bright yellow water-soluble dye from Phloroglucinol and diazotized 4-Methoxy aniline That is stable and also has a maximum absorption wavelength of 420 nm. With a molar absorptivity of 1.5989x 104l mol-1 cm-1 as well as index of Sand ell sensitivity 0.001 g.cm- 2, Beer's law is followed across a concentration range of (2-40) g.ml-1 of phloroglucinol.The ideal conditions for all color development are detailed, and even the suggested procedures for determining phloroglucinol in aqueous medium as well as some bulk sample  have been successfully employed.

This study included a simple, fast and sensitive method for estimating Amoxicillin (AMOX) in its pure state and in some of its pharmaceutical preparations, this method depends on the modified nanoparticles through oxidation and reduction reactions, With polyvinylpyrrolidone as a stabilizer in a base medium of sodium hydroxide, the (AMOX) drug act as effective reducing agents to dilute the ore mineral salt from silver nitrate (Ag +) to silver nanoparticles, the highest absorption of the oxidation-reduction reaction product of amoxicillin appears at 420 nm. the calibration curve was measured and the following information was calculated and showed compliance with the Beer-Lambert Law within the focus range 0.75-57.5 parts per million. Molar absorptivity was 9.3526 x 10−3 L / mol.cm, and Sandal’s sensitivity was 0.0448 μg/cm2, the standard deviation rate was 0.016%, and the correlation coefficient is 0.9994. The biological effect on some Gram-positive and Gram-negative bacteria was studied and the results were positive in the efficacy of the samples prepared on these bacteria.
