European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 7, Pages 4294-4300

This study is based on different IR spectra of nylon 6 and nylon 6.6 who are most common plastic in environment comes from domestic and industrial waste. Study is focused on amid II band (C=O stretch ) Amid I band (NH bending) NH stretch. Water filter for sampling and collection of debris from Harike wetland was done with help of plankton net in winter season. By using standard digestion and density separation methods suspected miscroplastic collected and analyzed by FTIR. IR spectra of both virgin and sample were matched and found that nylon 6 is present in Harike wetland. The source of Nylon may be lateral invasion or from different water bodies who are integral part of Harike wetland.

European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 7, Pages 4103-4113

Worldwide, several thousand tons of synthetic dyes are produced annually. The chemical or physico-chemical treatment methods are inefficient, expensive, have limited applicability, and cannot be applied to a large-scale effluent treatment process. The alternative approach is bioremediation, which is cheaper, sustainable, and eco-friendly technique. In present research two plausible bacterial isolates were selected to decolorize Scarlet RR dye. At static conditions, successful decolorization was achieved and decolorization percentage varied from 81% to 97, while at pH 7 and temperature 37 °C maximum decolorization is observed. Biodegradation of dye was confirmed by FTIR and GC-MS analysis. The present work can resolve leading problems touching contamination of the water bodies because of textile effluent discharge.

The present work describes the synthesis and characterization of Nd3+ doped magnesiummanganese
ferrite nanoparticles. A series of magnesium-manganese ferrites having
formula Mg0.9Mn0.1NdxFe2-xO4 (x = 0.1, 0.2, 0.3) has been prepared by SC method. X–ray
study has predicted the single phase configuration of the present ferrite nanoparticles. The
particle-size anticipated by means of Debye-Scherrer’s method is found to decrease (19.2-
13.5 nm). FTIR study has been carried out to understand the behaviour of M-O bonds
stretching. The band gap has been viewed to increase (4.60-6.11 eV) with the increase in
Nd3+ ions content

The Y-type hexaferrites Sr2CO2-XBixFe12O22 (x=0.0, 0.05 and 0.10) has been synthesized using Sol Gel technique. The structural and magnetic outcome of Bismuth dopant was investigated by XRD, FTIR and VSM study. The XRD reveal the formation of Y-type hexaferrite. Two prominent peaks were observed near 400-600 cm-1 in FTIR spectra indicates twisting and broadening of Fe-O bond at octahedral and tetrahedral sites, respectively. The squareness ratio (Mr/ Ms) of less than 0.5 for all compositions reveals that nanoparticles are haphazardly oriented multi domain particles.

The tris(thiourea)zinc sulphate (ZTS) and L-histidine doped ZTS (L-HZTS) single crystals were grown by evaporation technique. The unit cell dimensions were defined by single crystal XRD. The FTIR studies validated functional groups involvement and Vickers microhardness test has defined the mechanical properties. The optical and thermal properties were identified by UV-Vis spectrometer and TG/DTA respectively. The SHG efficiency was measured using powder technique.

Background:- the aim of the present study was to evaluate component of variety color of gallstone samples using Fourier Transform Infrared Spectroscopic Technique (FTIR) , also study the cost and simple method of Fourier Transform Infrared Spectroscopic Technique (FTIR) compare with result of quantitative chemical analysis like total cholesterol, calcium , total bilirubin , total protein . Material and method:- the material in the study were gallstones removed from 140 patient ( 94 female, 46 male) after surgical. All samples were stored in sterile dried counter and used for FTIR spectral analysis and quantitative chemical analysis. Result :-the results of FTIR were suggested that cholesterol and mixed gallstones content were a major component , cholesterol gallstones were characterized by the band 2949,1456,1053 cm -1 , while in mixed stones the band of cholesterol between 2800-3000 cm1 due to asymmetrical stretch vibration of CH2 and CH3group, and quantitative chemical analysis were explained the cholesterol stones and mixed stones were higher cholesterol compared to pigmented stones which were richer in total bilirubin and total protein. Conclusion:-the investigation were suggested thatFourier Transform Infrared Spectroscopic Technique (FTIR) is the less cost and simple method to find component of differential gallstone samples and this method conformed the cholesterol and mixed with calcium carbonate , bilirubin and total protein is the major component of human gallstones from Babylon,Iraq.
