Abstract: The corrosion inhibition of mild steel in sulphuric acid by flavonoids, separated from Nypa fruticans Wurmb leaves extract was studied using weight loss technique at 303K, 313K, 323K, 333K and 353K,. The constituents were separated by fractionation using Soxhlet apparatus after room temperature extraction with 70% acetone. The constituents were identified using standard functional group analysis (phytochemical screening) methods. The inhibitor concentrations of 0.1 g/L, 0.2 g/L, 0.3 g/L, 0.4 g/L and 0.5 g/L were used in 0.1M, 0.5M, 1M and 2M concentrations of acid solutions. Inhibition efficiency increased with increase in temperature and inhibitor concentration. Thus, maximum inhibition efficiency of 74.48% was obtained at the optimum temperature (323K) and concentration (0.5 g/L) for the flavonoid constituent. The flavonoid (catechin) separated from Nypa fruticans Wurmb leaves extract were used separately as efficient corrosion inhibitor of mild steel in H2SO4.

Abstract: Phuleli canal in Hyderabad is main water supply source for both irrigation as well as human drinking purpose. Quality of the canal deteriorates while passing through Hyderabad city,2nd largest city of Sindh ,Pakistan because highly toxic effluent from plastic factories, illigale cattle pens ,slaughterhouses and munciple sewage water are directly discharge into the phuleli canal without any treatment. Soil is a basic requirement for supporting the life on earth, but all over the world soil fertility decreasing by different ways including waste water and solid waste. In Pakistan soil is polluted by different ways out of which untreated liquid waste is main cause of soil pollution. The sewage and industrial liquid waste released in canals and streams without any treatment, which used for irrigation by which soil get polluted. This study was carried out to find out the facts about soil pollution by sewage, in this purpose Phuleli canal was selected, this canal carry the liquid waste of Hyderabad and for the desired study different parameters were investigated.
