TL;DR: In this paper, the seeds of Strychnos potatorum, pads of Cactus opuntia and mucilage extracted from the fruits of Coccinia indica in powder forms were applied to a water treatment sequence comprising coagulation-flocculation-sedimentations and filtration.
Abstract: In the present study the plant based coagulants namely, the seeds of Strychnos potatorum, pads of Cactus opuntia and mucilage extracted from the fruits of Coccinia indica in powder forms were applied to a water treatment sequence comprising coagulation-flocculation-sedimentationsand filtration. The study was conducted on synthetic turbid water created by kaolin. Emphasis was given to the filtration aspect of the treatment using synthetic turbid water. The performance of filter was defined by the quality of water and the head loss development across the filter bed. The optimum dose obtained from Batch coagulation-sedimentation test conducted for S. potatorum, Cactus and Coccinia indica were 1.5 mg/l, 30 mg/l, 0.5 mg/l were applied for filtration test and turbid waters with the supernatant turbidities obtained from batch coagulationsedimentation test (14 NTU in the case of S. potatorum, 17 NTU in the case of Cactus and 13 NTU in the case of Coccinia indica) were fed as an influent to the filter. The filtrate turbidities obtained after filtration were 0 NTU, 1NTU and 0 NTU which are lesser than 5 NTU (the guideline value recommended by WHO).Thus the use of natural coagulants improved the filtrate quality.

TL;DR: Isomotiol (fern-8-en-3β-ol) was isolated from the leaves of Strychnos potatorum; it was not known previously as a natural product, but it has been obtained by acidic isomerization of compounds with a fern-7-ene or fern 9(11)-ene skeleton as discussed by the authors.

TL;DR: In this article, the removal of Cr(VI) from aqueous solution using the seeds of the plant species Strychnos potatorum was studied, where the dried Nirmali seeds were powdered and used as adsorbent.
Abstract: The removal of Cr(VI) from aqueous solution using the seeds of the plant species Strychnos potatorum was studied. The plant is popularly known as Nirmali tree, grown all over India. The dried Nirmali seeds were powdered and used as adsorbent. The SEM-EDX and FT-IR spectrum of the adsorbent revealed that the powder is fibrous in nature and contains functional groups such as OH and COOH. The zeta potential measurements indicated negative surface charge beyond the pH of 1.50. Batch type experiments were conducted to study the influence of pH and initial Cr(VI) concentration on the removal of Cr(VI) from aqueous solutions. Maximum removal of Cr(VI) was observed at pH 1.0. The adsorption equilibrium was attained within a sort contact time of 4 min and the maximum uptake of Cr(VI) was found to be 59 mg g-1. The influence of anions such as Cl-, NO3-, and SO42- on Cr(VI) removal was investigated and found that the removal was slightly affected in the presence of NO3- and SO42-. The rate of removal of Cr(VI) was found to obey pseudo second order rate equation. The high free energy value of adsorption (ΔG = -137 kJ mol-1) indicated that the adsorption of Cr(VI) on Nirmali seed powder was mainly attributed due to chemical and electrostatic interaction. © 2011 American Institute of Chemical Engineers (AIChE).
