“…SBD-KNO 3 was produced by selective precipitation method using tartaric acid as precipitant from sea bittern (Ghara et al, 2014 ; Maiti et al, 2014 ) Tartaric acid was treated with bittern upon which selectively, potassium was precipitated as potassium bitartrate. Potassium bitartrate was decomposed by Mg(OH) 2 and HNO 3 to yield magnesium tartrate that precipitated as a solid and KNO 3 as liquor.…”

Aim: Many countries import potassic fertilizers due to dearth of K-mineral deposits. Therefore processes to obtain K-nutrient sources from sea bittern were developed by our Institute. The present investigation evaluated the fertilizer potential of three different sea bittern-derived (SBD) potassium forms developed viz., potassium schoenite, potassium nitrate and potassium ammonium sulfate on maize productivity in two cropping seasons.Methods: The pot and field experiments consisted of four treatments, wherein the three K forms were applied at the recommended rate of 40 kg K2O ha−1 and were compared with commercially used sulfate of potash. The effect of these fertilizers on different parameters of plant and soil were evaluated.Results: The application of SBD-potassic fertilizers led to enhancement in growth, productivity and quality of maize which related well with higher photosynthesis, nutrient uptake and soil quality parameters. On an average all the three forms of sea bittern-derived potash enhanced yield of maize over control by 22.3 and 23.8%, respectively, in pot and field trials. The best performance was under SBD-KNO3, which also recorded the highest benefit: cost ratio of 1.76.Conclusion: The K-fertilizers derived from sea-bittern—a waste product of salt industry—can thus be economically used to improve crop production sustainably.

“…This liquid is characterized by the presence of high concentrations of some salts, especially the harmful salts of boron, magnesium, calcium, and bromine, which affects the production of pure table salt, as this leads to an increase in sales in the land surrounding Qaraun Lake, which is transferred with the agricultural and sanitary drainage water of the governorate, as well as the rainwater to the lake. To increase the level of dissolved salts (TDS) from 34 to 44 grams/liter, which in turn affects the life of organisms and marine life in the lake [30].…”

The object of research in science and technology valleys and technology incubators, which for governments are the best investment of the scientific energies of scientists and innovators. As they are a link between research institutions and the industrial and service sectors, and as they transfer ideas and research results to different markets. This research aims to highlight the importance of Localization science and technology valleys and technological incubators related to nuclear activities, as they are one of the important tributaries to support the owners of the ideas of ambitious nuclear projects. The research also aims to shed light on the problems and obstacles that hinder the achievement of the desired goals of nuclear activities, such as: – the lack of information in the fields related to it; – the scarcity of expertise needed to implement it; – the lack of funding; – the absence of investors in this highly specific «nuclear» sector. The research presents the extent of the possibility of Localization those nuclear activities in Egypt through establishment valleys and incubators so that through this Localization there is an integrated environment of services and support that will ensure their development, raise their growth rates, and increase their efficiency. It is will lead to an increase in the chances of their success and sustainability, especially since Nuclear technology is used in many fields of industry, medicine, and agriculture. The research highlight the provisions of Egyptian Law regarding science, technology, and innovation incentives, as well as Egyptian Law establishing the Innovators Care Fund, to determine the possibility of establishing these valleys and incubators through the provisions of Egyptian legislation. Obtained results will have reached a great impact in encouraging investors and financiers to enter into technological partnerships with nuclear agencies in Egypt for the sake of safe investment in the elements associated with nuclear materials.

“…Bittern has been used directly as a supplement beverage (nigari) [1], fish preservatives [2,3], and industrial waste coagulant [4][5][6]. Indirectly, bittern is used as raw materials such as in fertilizer manufacture [7][8][9], the raw material for production of potassium salt [10,11], and manufacture of various magnesium compounds, such as magnesium oxide (MgO) [12], magnesium sulfate [13] and magnesium hydroxide (Mg(OH) 2 ) [14] .…”

This research was conducted to study the effect of dilution and electrolysis time on the recovery of Mg 2+ as Mg(OH) 2 from bittern by electrochemical method. The electrochemical process was carried out using 2-compartment electrochemical cell, connected by salt bridge prepared from NaCl suspended in gelatin. The experiment was carried out using nickel as cathode and carbon as an anode. The electrolysis process was carried out at a potential of 18 volts with dilution factors of 0, 2, 4, 6, and 8 times, and electrolysis time of 1, 2, 4, 6, 8, 10, and 12 hours. The results show that percent of conversion increased with dilution with the best result was obtained at 4x dilution factor and 4 hours electrolysis time with percent conversion of 85 % and purity of Mg(OH) 2 91%.
