Photocatalytic Treatment of Textile Industry Effluent having dyes using some Composite semiconductors

Sukumal Jain and Shiv Singh Dulawat,IJGHC, September 2017 – November 2017; Sec. A; Vol.6, No.4, 242-252,DOI: 10.24214/IJGHC/GC/6/4/24252.

In this research, the photocatalytic degradation of textile wastewater from Bhilwara textile industry in Rajasthan, India, using composite TiO2 and ZnO with different  ratio as photocatalysts was investigated. The experiments were carried out at 36oC in a stirrer bath reactor by using Ultra-Violet photo oxidation process. The effect of pH, time, amount of catalyst and ratio of composite TiO2 and ZnO was investigated and the optimized conditions for maximum amount of degradation were determined. The progress of reaction was observed spectrophotometrically. Titanium dioxide and zinc oxide proved to be very effective catalysts in photocatalytic degradation of real textile industrial water. The maximum decolorization achieved was 85.22% by using composite TiO2 and ZnO 1gm/l with (90:10) ratio at 36o C and pH of 8.5, within 150 minutes of irradiations. The results indicate that for real textile wastewater, composite TiO2 and ZnO (90:10) ratio is comparatively more effective than only TiO2 or only ZnO. This study proves that real textile wastewater reacts differently to catalysts than aqueous solution of azo-dyes, which is associated with surface steps and sensitization of the reaction rate by presence of other contaminants in real textile wastewater 

Phytotoxicity assessment of petrochemical industry effluent and phytoremediation potential of plants growing naturally at contamination site

Sangeeta Anand, Dhananjay Kumar, Sushil Kumar Bharti and Narendra Kumar,IJGHC, September 2017 – November 2017; Sec. A; Vol.6, No.4, 232-241,DOI: 10.24214/IJGHC/GC/6/4/23241.

Petrochemical industry effluent was analysed for various physicochemical characteristics including heavy metals (Cd, Cu, Pb, Ni, Cr, Hg, Zn, Mn and Fe). The toxicity of the petrochemical industry effluent was tested on seeds of rice (Basmati - 198, Push sugandh and Sambhamasuri), pulse (Chick pea K-3256, Mung N-1, Masoor VL-1) and oil seeds (Mustard BR-40, Alsi KL-43, Seasame G til-3). Radicle growth, germination index, phytotoxicity, metal tolerance index at the germination stage was recorded in seeds exposed to wastewater. Toxicity (%) was found to be maximum in Basmati-198 and linseed B-67 i.e.71.8 and 26.85% and minimum in pusa sugandh and mung-N-1 i.e. 46.6 and 18.35 % at 100 and 50% of effluent concentration respectively. Plants growing naturally viz. Phyllanthus amarus, Sida cardifolia and Cucumis sativus at industrial site were evaluated for metal accumulation and for the purpose of phytoremediation. Results revealed that S. cardifolia is capable for remediation of metals viz. Fe, Zn, Pb, Mn, Cu, Cd, Ni and Cr from contaminated site and can be used for phytoremediation.

Phytochemical Studies and Anti-Oxidant Activity of the Barnyard Millet - “Echinochloa Frumentaceae Link”

G.Abirami S.Revathi, R.Rajalakshmi. S.Pushpanjali, R.Saranya,IJGHC, September 2017 – November 2017; Sec. A; Vol.6, No.4, 224-231.DOI: 10.24214/IJGHC/GC/6/4/22431.

The aim of present investigation was to determine the chemical composition and Antioxidant activity of millet and the recent advances in research carried out to date for purposes of evaluation of nutritional quality and potential health benefits of millet grains. The present study is to analyze the presence of Phytochemical and Pharmagonostical screening such as Microscopy, Ash value, Moisture content, Extraction of Millet and Identification test were studied using various solvents. In vitro study of Antioxidant activity was carried out by using Hydrogen peroxide Scavenging method. A Phytochemical profile of selected plant Millet was Barnyard millet “Echinochloa frumentaceae link” (EF) belongs to Family Poaceae. The aim of this article is to work the latest scientific research on Millet, with the hope that it will continue.

Study of pollen morphology in some plants

Anil A. Kshirsagar,IJGHC, September 2017 – November 2017; Sec. A; Vol.6, No.4, 218-223.,DOI: 10.24214/IJGHC/GC/6/4/21823.

The present paper deals with the study of 15 plants belonging to 11 different families confined to palynological studies (pollen morphology). The pollen morphology of selected plants indicates that the pollens are varies in shape and size. The pollen type is mainly Monoporate, Tri-periporate, Colporate, Trizonocolpate, Tricolpate, Prolate, Winged are noted in such a selected plant species. The symmetry is radial, bilateral and spiny radial etc

Evaluation of Physico-Chemical Parameters and Tracemetal Contents of Ground Water of Jaipur City during Post Monsoon Season 2016

Sunita Prajapati, IJGHC, September 2017 – November 2017; Sec. A; Vol.6, No.4, 213-217.,DOI: 10.24214/IJGHC/GC/6/4/21317

The physico-chemical parameters with trace metals of the ground water of different areas like Mansarovar, Malviya Nagar, Jawahar Nagar and Shastri Nagar of Jaipur city during the post monsoon season of the year 2016, have been analaysed. This study was conducted to determine the water quality of ground water which is used for drinking in the study area. The alkanity and total hardness are marginally high but are in acceptable range. The B.O.D and C.O.D. are under standard limits in the study areas. However it needs some degree of treatment before consumption
