Item High grade epsom salt from sea bittern(2011-11-30T04:45:35Z) Gadre, G.T.; Bhavnagary, H.M.; Lele, V.N.Item Minor constituents of indian sea-water(2011-11-24T11:05:28Z) Kappanna, A.N.; Gadre, G.T.; Bhavnagary, H.M.; Joshi, J.M.The quantities of nine minor constituents in indian sea-water (bhavnagar coast) were reported in an earlier note.1 the present communication deals with the estimation of fourteen minor elements, including the nine reported earlier, and the analytical procedures followed.Item Minor constituents of sea-water(2011-11-23T11:35:07Z) Kappanna, A.N.; Gadre, G.T.; Bhavnagary, H.M.; Joshi, J.M.Data on the minor constituents in sea-water are of interest from the viewpoint of chemical oceanography. published work shows that the concentration of minor constituents vary to a constituents from region to region depending upon seasons and the wealth of the organic populations near the coast.Item Potassium chloride and magnesium sulphate from sea bittern(2011-11-24T06:09:21Z) Gadre, G.T.; Bhavnagary, H.M.An integrated process for extraction of fertillizer grade potassium chloride and megnesium sulphate (epsom salt) from sea bittern, left afeter the extraction of sodium chloride, has been developed on a semipilot plant scale at the institute. india's potassim chloride require ments of about 50,000 tons a year are almost entirely met by imports at present.Item Potassium chloride from sea bittern : part I(2011-11-22T09:51:28Z) Gadre, G.T.; Rao, A.V.; Bhavnagary, H.M.A process has been worked out by which potassium chloride of 97-99 per cent purity can be obtained from the waste bittern of the marine salt industry. the desulphation of the bittern is carried out using commercial calcium chloride.sulphate-free bittern deposits, on concentration, the double salt, KCL.MGCL2.6H2O,from which potassium chloride is recovered by leaching it with cold water or by cooling a supersaturated solotion of the double salt.Item Potassium chloride from sea bittern : part I(2011-11-22T09:35:16Z) Gadre, G.T.; Rao, A.V.; Bhavnagary, H.M.A process has been worked out by which potassium chloride of 97-99 per cent purity can be obtained from the waste bittern of the marine salt industry. the desulphation of the bittern is carried out using commercial,calcium chloride. sulphate-free bittern deposits,on concentration,the double salt,KCL.MGCL2.6H2O, from which potassium chloride is recovered by leaching it with cold water or by cooling a supersaturated solution of the double salt.Item Potassium chloride from sea bittern: part II - recovery of potassium chloride, magnesium sulphate & potassium sulphate(2011-11-23T04:49:21Z) Gadre, G.T.; Rao, A.V.; Bhavnagary, H.M.Optimum conditions for(i)separation of magnesium sulphate from sea bittern, (ii) treatment of desulphated bittern for the recovery of potassium chloride and (iii) preparation of potassium sulphate from magnesium sulphate by double decomposition with potassium chloride have been determined.Item Potassium chloride from sea bitterns(2011-11-23T09:05:01Z) Gadre, G.T.; Bhavnagary, H.M.; Rao, A.V.A simple and economical process is described for the recovery of potassium from sea bitterns, which are now let to waste.Item Potassium sulphate from sea bitterns(2011-11-23T11:08:45Z) Bhavnagary, H.M.; Gadre, G.T.Sea bittern left over after the recovery of common salt from sea water, at present allowed to go waste is rich in potassium chloride which can be recovered from the bittern by fractional crystallization. the salt as such, without purification,finds use in the preparation of mixed fertilizer. crops like potato, clover, tobacco, beet, etc. do not tolerate chloride and in these cases chloride-free potassium sulphate is employed.Item Preparation of potassium carbonate by the engel-precht method using sodium bicarbonate(1968) Bhavnagary, H.M.Item Separation of calcium & magnesium in sea water from sodium & potassium with a phenolsulphonic cation exchanger(NISCAIR, 1967) Bhavnagary, H.M.; Krishnaswamy, N.Item sulphate content in the bitterns from salt works in kuda (kutch) Region(Reprinted from salt research industry, 1965) Mehta, P.R.; Bhatt, M.M.; Bhavnagary, H.M.; Gadre, G.T.
