Adsorption of Reactive Dyes from Textile Wastewater Using Corn Stalk Activated Carbon

Robel Legese Meko

Extensive use of synthetic dyes in textile industry has created a major pollution problem. Among various treatments, adsorption has been considered as a better process due to its effectiveness of removing color from wastewater. In this present work, the efficiency of activated carbon prepared from corn stalk for removal of reactive dye from textile wastewater was studied. Corn stalk was chemically activated with KOH, followed by carbonizing in a muffle furnace. The carbonized corn stalk was characterized by SEM and FTIR spectroscopy. Adsorption of three reactive dyes were carried out by preparing dye samples in laboratory and taking dye wastewater from BDTSC. Adsorption was carried out under the control of three different factors namely contact time, adsorbent dosage and pH. Optimum time, pH and adsorbent dosage for adsorption process were found to be 60 minutes, 3.8 pH and 4 g/L respectively. Using those optimum operating parameters, the adsorption capacity of prepared activated carbon for Reactive yellow-145, Reactive red-2, Reactive blue-19 and wastewater taken from BDTSC was 96.9%, 95.5%, 97.1% and 88% respectively. Langmuir and Freundlich adsorption isotherm models were used to simulate the equilibrium data for the adsorption process. The result indicates that the adsorption process best fits with Freundlich isotherm. The produce activated carbon was also shown a reduction of BOD, COD, TDS, TSS and turbidity.

Preparation and Characterization of Polypropylene Nonwoven fabric incorporated Silica Aerogel Composite dried in Ambient Pressure Drying Method

Kazi Md Hasanul Hoque

In recent times, sustainable ecofriendly thermo-insulation materials which are flexible and mechanically robust have grabbed worldwide remark. Nonwoven fabric and aerogel have complementary characteristics needed for desirable thermal insulation. In this research, silica aerogel/polypropylene (PP) nonwoven fabric composite with desirable properties was synthesized via a two-step sol-gel process through immersing the PP nonwoven fabric into silica sol. After in situ gelation, silica phase was hydrophobized with hexamethyldisilazane, and the composites were dried at ambient pressure method. Scanning electron microscopy (SEM), DSC, TGA were used for the characterization of the composites. The contact angle and heat conducting performance of the composites were also determined. The results show that silica aerogel particles were efficiently covered the surface of the PP non-woven fabric and completely filled the micron size pores of the nonwoven fabric leading to a stronger hydrophobicity and higher thermal insulation performance in the aerogel composite. The findings in this study are significant and can be used for further research in aerogel-treated nonwoven fabrics.

The Role of Binders and Its Chemistry in Textile Pigment Printing

Asaye Dessie,Bezaneh Eshetu

This review paper presents the chemistry of binders and their action in pigment printing of cellulosic textile substrate.  Printing of textile materials is probably best described as an industrial art, having a long history and an assured future. Textile printing is the most versatile and important of the methods used for introducing color and design to textile fabrics. In pigment printing, insoluble pigments, which have no affinity for fibers, are fixed on to the fibers with binding agents or binders.  In textile printing, dyes or pigment are transferred to textile fabric by printing pastes. Binders are the mechanism used to keep the color on the fabric when using pigments for printing textiles. The choice of binders will always depend upon the final fastness requirements as well as the cost requirements of the process. Almost all the binders used in textile pigment printing are the addition polymerization products. The binder is a film forming substance made up of long chain macromolecules, which when applied to the textile together with the pigment , produce a three dimensionally network. Different binders were also developed for the purpose, resulting finally in the use of water- in-oil, and oil-in-water emulsions. This greatly accelerated the use of pigments in textile printing and then pigments have become major coloring matters used in printings. This paper review gives more emphasis on the need and functions of binder in pigment printing and also the chemistry of binders and its action in fixation of the pigment onto the textile substrate.

Rare earth salts mediated improved rubbing fastness for Indigo dye

Padma S Vankar, Archana Gangwar

Indigo dye though rich in blue colour has poor affinity for cellulose cannot penetrate too well and thus it mostly remains at the surface of the fabric after dyeing. This phenomenon is called ring dyeing. Such ring-dyed materials have poor rubbing fastness towards dry and wet test methods. Our objective in this paper has been to use rare earth (RE) salts to overcome the rubbing fastness problem. The RE metals used in this research work are Cerous sulphate, Lanthanum chloride and Yttrium chloride.

COPPER-COATED UNIFORM FOR HEALTH CARE PROFESSIONAL COULD HELP REDUCE CROSS INFECTION IN HOSPITALS

Kumar Vijay, Kumawat Nitesh, Ramawat Yashawant, Sharma Ankur

Nosocomial Infections are a more common health issue in each health care setting across the worldwide. Pathogenic flora spread throughout medical and surgical care facilities on surfaces and uniforms, contributing to damage both of human life and money. These issue turn into worse still after increase of drug resistance in most of the strains, which is rendering the broadspectrum antibiotic more powerless. So we require another ways instead of antibiotics. Precious metal is also a key role in great antibacterial and antimicrobial agents such as gold, silver and copper, which have superb antimicrobial properties. Gold or silver are more expensive for use against infection as compare to copper. Copper is good option that we can use in view of cost as well as copper having very good at killing power for pathogenic flora.
