Free radicals from cigarette smoke are a dangerous part that must be found to counteract. This research aims to make a composite biofilter made from Azadirachta Indica to ward off/capture free radicals from cigarette smoke. This biofilter is made with Azadirachta Indica leaf powder added to polyethylene glycol as the matrix. The biofilter was then seen for its physical characteristics; the density and porosity were tested using SEM. Furthermore, a biofilter membrane is used to filter cigarette smoke. Cigarette smoke that passes through the biofilter is then analyzed using ESR for its free radical content. The results showed that the biofilter made from Azadirachta Indica leaves could absorb several types of suspected free radicals in cigarette smoke. Biofilters using PEG as a matrix with a mass of 0.9 and 1gr were the most effective in absorbing the suspected types of free radicals. SEM test showed an average pore size of 2-3 µm for a mass of 1gr with PEG as the matrix.

“…The results of ESR on non-filter kretek cigarettes are presented in the following A biofilter composite membrane made from bidara leaf powder was installed and data was collected 4 times with variations in the mass of bidara leaf powder and PEG matrix, the ESR results were obtained as follows: Free radicals in cigarette smoke have two different populations, in the tar phase and in the gas phase (Sukmaningsih, Permana, Santjojo, Wardoyo, & Sumitro, 2019). The tar phase contains several relatively stable free radicals, while the gas phase of cigarette smoke contains small radicals centered on oxygen and carbon which are much more reactive than the tar phase radicals.…”

A number of diseases have been stigmatized as a side effect of smoking and its smoke. Reducing the dangers of smoking by capturing radioactive substances from cigarette smoke is one way to reduce or reduce the level of danger. This study aims to make a filter made from bidara leaf powder to bind free radicals in cigarette smoke. Bidara leaf powder with PEG solution was mixed and stirred until homogeneous with variations in the mass of bidara powder 0.7 grams, 0.8 grams, 0.8 grams, 0.9 grams and 1 gram. The product was molded with a 0.7 cm diameter pipe hose, allowed to dry before being removed from the mold, and heated at a temperature of 105o C for 20 minutes. Biofilter matrix using polyethylene glycol (PEG) and egg white, bidara leaf powder as a biofilter filler. The physical characteristics of the membrane were obtained by conducting density and porosity tests with SEM. The effectiveness of the biofilter membrane is known by passing cigarette smoke, then the number of free radicals trapped in the biofilter is analyzed using ESR. The results showed that the use of a biofilter made from bidara leaf powder with a mass of 0.9 grams with an egg white matrix was able to bind 85.7% of free radicals (C, O2-, C, Peroxy, CO2-, and Hydroperoxides) with 100% effectiveness, density. 0.893 g/cm3 and porosity 0.6788%. Testing the characteristics of the biofilter with SEM (Scanning Electron Microscopy) shows the size of the biofilter pores between 2-3 m, while the size of free radicals in cigarette smoke ranges from 20-430 nm. This indicates that the ability to bind free radicals in cigarette smoke is influenced by the antioxidant activity of bidara leaf powder (filler biofilter).

“…1 (ii). Presence of numerous vibrational peaks can be seen in the FT-IR spectrum where a broad peak in the range of 3551–3225 cm −1 is attributed to the O–H stretching and C–O stretching (carboxylic acid) 33 . The band observed at ~ 2938 cm −1 is corresponding to C–H stretching, a small intensity peak appeared at ~ 2353 cm −1 is related to the C=C stretching whereas the peak recorded ~ 1733 cm −1 could be correlated to the –C=O stretching of the aliphatic esters.…”

Synthesis of nanomaterials following green routes have drawn much attention in recent years due to the low cost, easy and eco-friendly approaches involved therein. Therefore, the current study is focused towards the synthesis of Fe3O4/α-Fe2O3 nanocomposite using waste pulp of Jamun (Syzygium cumini) and iron nitrate as the precursor of iron in an eco-friendly way. The synthesized Fe3O4/α-Fe2O3 nanocomposite has been extensively characterized through numerous techniques to explore the physicochemical properties, including X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, Ultraviolet-Vis spectroscopy, field emission scanning electron microscope, high resolution transmission electron microscope and vibrating sample magnetometer. Further, efficiency of the Fe3O4/α-Fe2O3 nanocomposite has been evaluated to improve the incubation temperature, thermal/pH stability of the crude cellulase enzymes obtained from the lab isolate fungal strain Cladosporium cladosporioides NS2 via solid state fermentation. It is found that the presence of 0.5% Fe3O4/α-Fe2O3 nanocomposite showed optimum incubation temperature and thermal stability in the long temperature range of 50–60 °C for 15 h along with improved pH stability in the range of pH 3.5–6.0. The presented study may have potential application in bioconversion of waste biomass at high temperature and broad pH range.
