Batch equilibrium technique was carried out under the influence of solution pH, contact time, sorbent dosage, initial metal concentration and competitive study. The maximum metal ions capacity (Ca2+, Mg2+) values were identified as 171.2 and 193.6, respectively. Sorption equilibrium was established in 24   hr and the data were described by both Langmuir and Freundlich models. The potential application of this sorbent for water treatment and metal ions removal from water samples is successfully accomplished UR - https://www.ijabbr.com/article_7883.html L1 - https://www.ijabbr.com/article_7883_4b77372117d32a21b39662c8087b72fc.pdf ER -
