  Abstract: This research was carried out to extract and purify phycocyan in from blue algae from Chaohu Lake by utilizing salting out methods. Thus a two-step salting out was performed using Ammonium sulphate, Triammonium citrate, Sodium citrate and Sodium sulfate. The phycocyanin and the impurity solution collected at each phase were subjected to analysis by using UV-Vis spectrophotometer to identify the optimal dose of ammonium sulfate, triammonium citrate, sodium citrate and sodium sulfate. The optimal molar concentration for Ammonium sulphate, Triammonium citrate, Sodium citrate and Sodium sulfate in the first and second salting out process were 1.0 mol/L and 1.7mol/L for Ammonium sulphate (NH4)2SO4, 0.7, mol/L and 1.3 mol/L for Triammonium citrate C6H17N3O7, 0.5mol/L and 0.9 mol/L for Sodium citrate C6H5Na3O7, 1.0mol/L and 1.3 mol/L for Sodium sulfate Na2S04. After the two-step salting out processes, it was observed that higher molar concentrations can remove impurities in large quantities, and both purity and yield was greatly increased. The results indicate a purity of phycocyanin above 2.0 with a phycocyanin recovery relatively high. This was carried out to affirm and estimate if result from the salt use will vary from a previous experiment carried out on the same river by the authors with three (3) different kinds of salt K3C6H5O7H2O, C6H5O7(NH4)3 and (NH4)2SO4 as compared to the four (4) salt compound used in this experiment.

as a Future Solution

  Abstract: Day after day the world stuck more and more in wars, pollution and so many other risk that threaten the environment. With a population of more than 7.3 billion, the planet suffers from continuous damage from human activity. As a result of these human distortions, climate change is one of the most fatal challenges that face the world. Climate Change won’t be stopped or slowed by a single action, but with the help of too many small contributions from different fields, it will have an impressive impact. Changing to electricity generation, manufacturing, and transportation generate most headlines, but the technology field can also play a critical role. The Internet of Things (IoT) in particular, has the potential to reduce greenhouse emissions and help slow the rise of global temperatures. IoT includes more than super brilliant new gadgets and smart widgets. It also influences the Earth's condition, from its available resources to its climate. In this paper we are showing that technology itself could be the tool will save the world if we take advantage of it. Environmental monitoring is a broad application for the Internet of Things (IoT). It involves everything from watching levels of ozone in a meat packing facility to watching national forests for smoke. These solutions are the first step toward creating a numerous connected infrastructures to support innovative services, better flexibility and efficiency. We also make a spot on Industrial Internet of Things (IIoT) and its challenges as the future is for it.
