Rapid and facile preparation of the cheap modified electrode materials is an important parameter in development of the efficient electrochemical sensor for industrial scale production and mass-market usage. In the present work, the carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) was prepared for sensitive determination of lead (Pb) ion in the presence of bismuth (Bi)...

• Spindle shaped PbWO 4 nanostructure with enhanced photocatalytic activity was obtained by facile and green sonochemical way for the first time. Maltose as a new capping agent utilized. Sonication time, dose of precursors, power ultrasound waves kind were optimized. The made lead tungstate samples in role visible-light photocatalyst applied to remove organic pollution water. Usage ultrasonic i...

abstract:background and objectives:in arid and semi-arid regions, salinity is a serious and chronic problem for agriculture. due to the improved methods of irrigation and mechanization this methods to increase water use efficiency and enhance the uniformity of water distribution in the field, is very important. main area of farming cotton in iran is about 150000 ha, which in kerman province mos...

The increasing demands on drinkable water, along with population growth, water-intensive agriculture and economic development, pose critical challenges to water sustainability. New techniques to long-term water conservation that incorporate principles of sustainability are expected. Recent studies have shown that providing customers with usage information of fixtures could help them save a cons...

Water monitoring in households is important to ensure the sustainability of fresh water reserves on our planet. It provides stakeholders with the statistics required to formulate optimal strategies in residential water management. However, this should not be prohibitive and appliance-level water monitoring cannot practically be achieved by deploying sensors on every faucet or water-consuming de...
