Permeation of Cu（Ⅱ） from its aqueous solution through a supported liquid membrane （SLM） containing di（2-ethylhexyl）phosphoric acid （D2EHPA） carrier dissolved in coconut oil has been studied. the effects of Cu（Ⅱ）, pH （in feed）, H2SO4 （stripping） and D2EHPA （in membrane） concentrations have been investigated. the stability of the D2EHPA-coconut oil has also been evaluated. High Cu（Ⅱ） concentration in the feed leads to an increase in flux from 4.1 × 10^-9 to 8.9 × 10^-9 mol/（m^2·s） within the Cu（Ⅱ） concentration range 7.8×10^-4-78.6×10^-4 mol/L at pH of 4.0 in the feed and 12.4 × 10^-4 mol/L D2EHPA in the membrane phase. Increase in H2SO4 concentration in strip solution leads to an increase in copper ions flux up to 0.25 mol/L H2SO4, providing a maximum flux of 7.4 × 10^-9 mol/（m^2·s）. the optimum conditions for Cu（Ⅱ） transport are, pH of feed 4.0, 0.25 mol/L H2SO4 in strip phase and 12.4 × 10^-4 mol/L D2EHPA （membrane） in 0.5 μm pore size polytetrafluoroethylene （PtFE） membrane. It has been observed that Cu（Ⅱ） flux across the membrane tends to increase with the concentration of copper ions. Application of the method developed to copper plating bath rinse solutions has been found to be successful in the recovery of Cu（Ⅱ）.

A dual input LED lighting scheme with constant illumination is proposed in this paper. the scheme employs a photovoltaic array as the first input and a battery as the second one. A microcontroller is programmed to operate a changeover switch as well as a DC-DC converter for uninterrupted and constant illumina- tion in work place. the scheme is suitable for conference halls, laboratories, clean rooms, marriage halls, theaters, etc. the complete modeling, design and experimentation of the proposed scheme are explained and the economic viability of the scheme is justified.

India＇s surface water and groundwater distribu- tion is temporally variable due to the monsoon. Agriculture is one of the dominant economic sectors in India. Groundwater quality is regularly assessed to determine usability for drinking and irrigation. In this study, World Health Organization and Bureau of Indian Standards guidelines were used to determine suitability of ground- water near artificial recharge structures （ARS） with a focus on the structureg impact on groundwater quality. Ground- water resources were evaluated for irrigation suitability using electrical conductivity （EC）, sodium adsorption ratio, the US Salinity Laboratory diagram, sodium concentration, Wilcox＇s diagram, Kelly＇s index, and Doneen＇s perme- ability index. EC and major ions were tested in recharge areas at different distances from the ARS. the construction of ARS at optimal distances along major streams has improved groundwater quantity and quality in the subbasin. Before construction of ARS, fluoride concentrations were higher; after construction, fluoride was reduced in most locations. Water stored in the check dam and groundwater in the wells closer to the structure were suitable for both drinking and irrigation purposes. Impact of ARS on nearby groundwater quality was observed at Pal- lipatti, Mulayanur, Venkadasamuthram, Pudupatti, Poyyappatti, Harurl, and Sekkampatti. More distant sites included Pappiredipatti, Nambiyappati, Menasi, Harur, todampatti, and Adikarapatfi. Data demonstrated improved groundwater quality in the area of the ARS. through recharge, the non-potable fluoride in the region is reduced to the permissible limit for human consumption.
