Item Boron content insea brine, bittern and marine byproducts(csmcri bhavnagr, 1970) Dhandhukia, M.M.; Seshadri, K.Item Byproduct recovery from saline lakes and alkaline soils1(indian arid zone ,, 1964) Seshadri, K.; Datar, D.S.Item Constituents of sambhar lake brine(2011-11-24T07:05:19Z) Seshadri, K.; Langalia, J.K.Shambhar lake brin of densties 10' and 30'Be has been analysed emoloying the microanalytical techniques for the minor constituents.NaCl, Na2SO4,Na2CO3, and NaHCO3, from the major constituents(98.4 per cent and the minor constituents(KCl, Na2B4O7,Na3PO4, NaBr, LiCl, As2O3, NH3, CaO, Na2S and in-solubles) form only 1.6 per cent of the total salts. the minor constituents do not attain any significant concentration at 30'Be,Mg,Ba,Sr,Sb,Cu,Fe and Al are not present even in micro quantities in these brine samples.Item detection separation and estimation of rubjdium in presence of potassium by paper chromatography(csmcri bhavnagar, 1970) Baxi, D.R.; Seshadri, K.Item Exploitation of sambhar lake bitterns(2011-11-23T09:36:49Z) Seshadri, K.; Buch, S.D.A process for recovering sodium solphate, sodium chloride and sodium carbonate from hquid and solld bitterns and sub-standard salt,worked out on the basls of phase rule studles, is described. it consists of the following steps:(1)elimination of algae from the liquid bittern or aqueous extracts of solid bitterns by chlorine treatment;(2)adjustment of the composition of the solution and chilling it to 0'C.;(3)separation of Na2SO4.10H2O by centrifuging;(4)dehydration and purification of sodium sulphate by solar heat;(5)recovery of sodium chloride by solar evaporation of desulphated llquor until the liquid reaches 10 per cent sodium carbonate strength;and(6)carbonation of the desalted liquor for the recovery of sodium carbonate as bicarbonate.Item Exploitation of sambhar pan crust(2011-11-23T09:53:45Z) Seshadri, K.; Buch, S.D.Tree method based on solubility data have been worked out for the recovery of sodium sulphate from the sambhar lake pan crust. ninety per cent of sodium sulphate present in the crust is recovered as technical grade quality sodium sulphate by the chilling process, 65-73 per cent by adding solid sodium chloride at 50'C.to the solution prepared from the crust and 75-80 per cent from the upgraded crust obtained by digesting it with water.Item Exploitation of sambhar pan crust(2011-11-23T05:37:37Z) Seshadri, K.; Buch, S.D.Item Exploitation of the natural sodium sulphate resources(2011-12-12T06:55:52Z) Seshadri, K.Item Improved recovery of sodium sulphate from sambhar bittern by gypsum treatment(2011-11-23T10:54:47Z) Seshadri, K.; Vyas, R.P.The possibility of enriching the sulphae content of sambhar lake bittern by treatment with gypsum has been investigated as bittern with a higher concentration of sulphate can be processed economically for the recovery of sodium sulphate. treatment of the bittetn with finely powdered gypsum (80 per cent passing through 100 B.S mesh) has been found to convert sodium carbonate in the bittern to sodium sulphate and raise the concentration of sodium sulphate from 8 to 13 per cent. on chilling the enriched bittern to 0'C., higher yields of sodium sulphate are obtained, representing about 60 per cent higher recovery over that obtained with untreated bittern.Item Manufacture of potash alum(1967) Bhat, G.D.; Sanghavi, J.R; Seshadri, K.; Datar, D.S.Item Manufacture of potash fertilisers(2011-11-30T05:43:46Z) Seshadri, K.Item Mixed salt production at tuticorin(csmcri bhavnagr, 1969) Seshadri, K.; subramaniam, P.Item Phase rule study of quaternary system kcl-alcl3-MgCl2-H2O at 25 C.(NISCAIR, 1968) Patel, K.P.; Seshadri, K.Item Polytherm of the quaternary system sodium chloride-sodium sulphate-sodium carbonate-water(2011-11-30T05:56:13Z) Seshadri, K.; Lobo, J.Item potassium chloride from the residue of saltpetre industry(2011-12-15T11:25:33Z) Joshi, J.M.; Seshadri, K.Item Potassium chloride recovery from mixed salt using distiller waste liquor of soda ash plant(1966) Joshi, J.M.; Sanghavi, J.B.; Seshadri, K.Item Potassium phosphate fertiliser(csmcri bhavnagar, 1969) Oza, M.R.; Seshadri, K.Item Pottassium sulphate from syngenite(csmcri bhavnagar, 1969) Patel, K.P.; Vyas, R.P.; Seshadri, K.Item Prepartion of schoenites from the mixed salt obtained from marine bittern(csmcri bhavnagar, 1968) Choudhari, B.P.; Seshadri, K.Item Prevention of caking in fertilizer grade potassium chloride(2011-11-30T06:13:16Z) Seshadri, K.; Chauhan, B.P.; Oza, M.R.
