Adsorption of lead (II) ions onto cassava starch 5-choloromethyl-8-hydroxyquinoline polymer (CSCMQ) was investigated with the variation in the parameters of pH, contact time, lead (II) ions concentration, temperature and the adsorbent dose. The Langmuir and Freundlich models have been applied. CSCMQ was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. Results showed that the adsorption process was better described by the Langmuir model. Adsorption kinetics data obtained for the metal ions sorption were investigated using pseudo-first-order, pseudo-second-order and intraparticle diffusion model. The maximum adsorption capacities (qm) were 46.512, 43.859 and 42.735 mg/g at 25, 35 and 45 °C, respectively. The dynamical data fit well with the second-order kinetics model. The results indicate that CSCMQ could be employed as low-cost material for the adsorption of Pb(II) ions from aqueous medium.
5 ways to conserve water this winter
Water conservation is something we harp on during the summertime, but what about during the winter? When the irrigation systems shut down, it’s easy toput conservation on the back burner while indoor water waste continues to occur. According to the U.S. Geological Survey, the average person uses 80-100 gallons per day for everything from cooking, to showering and flushing the toilet. While there are a number of ways to integrate water conservation into your daily routine, here are five tips that will...

5 Ways to Deliver Driver Debriefs Like a Pro
Without exception, every transport operation debriefs drivers in one way or another. For some it’s informal and ad hoc – for others it is a more formal process. Either way debriefs are very important to understand when and why routes and schedules aren’t being adhered to, or driver performance is not up to standard.This is vital to know if and how improvements can be made to achieve the very best customer experience. The Debrief is also the driver’s opportunity to raise any issues with...
